YieldReaction ConditionsOperation in experiment
99% 6-(benzyloxy)-4-chloro-7-methoxyquinazoline: Preparation 10 (4.85 g, 17.2 mmol) in phosphorous oxychioride (25 mL) was heated to 12O0C for 3 h. After cooling to room temperature, the phosphorous oxychioride was removed in vacuo, the residue was slowly added to saturated aqueous potassium carbonate and the mixture was stirred until bubbling ceased. The aqueous mixture was extracted with chloroform, the organic layer was washed with brine, was dried over magnesium sulfate, was filtered, and was concentrated to afford 5.1 g (99% yield) of the title compound; MS (AP/CI): 301.1 , 303.1 (M+H)+.
72% With sodium hydroxide; N-ethyl-N,N-diisopropylamine; trichlorophosphate; Production Example 30: 6-(Benzyloxy)-4-chloro-7-methoxyquinazoline Phosphorus oxychloride (3.1 ml) was added to <strong>[286371-64-0]6-(benzyloxy)-7-methoxy-3,4-dihydro-4-quinazolinone</strong> (3.5 g) and diisopropylethylamine (11.5 ml). The mixture was refluxed for 20 min. The reaction solution was cooled to room temperature, and a 10% aqueous sodium hydroxide solution was then added to the cooled reaction solution, followed by extraction with chloroform. The organic layer was dried over sodium sulfate. The organic layer was filtered, and the solvent was then removed by distillation under the reduced pressure. The residue was dried through a vacuum pump to give 2.9 g (yield 72%) of the title compound. 1H-NMR (CDCl3, 400 MHz): delta 4.07 (s, 3H), 5.32 (s, 2H), 7.35 - 7.53 (m, 7H), 8.86 (s, 1H)
With N-ethyl-N,N-diisopropylamine; trichlorophosphate; for 0.5h;Heating / reflux; EXAMPLE 20; N-(3-chloro-4-fluorophenyl)-7-methoxy-6-[3-(5,8-Dioxa-10-azadispiro[2.0.4.3]undecane) propoxy]quinazolin-4-amine 2-Amino-4-methoxy-5-benzyloxybenzamide (JMC, 20, 146) (5 g) was mixed with triethylorthoformate (15 ml) and refluxed overnight. The reaction solution was cooled and triturated with EtOAc (40 ml) then filtered to give <strong>[286371-64-0]7-methoxy-6-benzyloxyquinazolone</strong> (3.2 g). This product was mixed with DIPEA (15 ml) and to the solution was added POCl3 (3 ml) slowly. The reaction mixture was refluxed for 30 minutes and cooled, then poured into a stirred mixture of ice and CHCl3. The solution was further extracted with CHCl3 three times and washed with H2O followed by brine, dried over Na2SO4 and evaporated to give a light brown solid as the chloride for next step without further purification. The above chloride (2 g) was mixed with 3-chloro-4-flouroaniline (1.3 g) in 2-propanol (30 ml) and the reaction was refluxed for 2 hours and cooled to RT. The precipitate was filtered and mixed with TFA (4 ml) and refluxed for 1 hour. The solvent was evaporated under reduced pressure and the residue was washed with EtOAc to furnish N-(3-chloro4-fluorophenyl)-7-methoxy-6-hydroxy-quinazolin-4-amine (1.3 g) that was mixed with K2CO3 (1.1 g) and 3-bromopropanol (850 muL) in DMF (5 ml). The reaction was heated at 80 C. overnight and poured into water and the precipitate was filtered to give N-(3-chloro4-fluorophenyl)-7-methoxy-6-(2-hydroxyethoxy)-quinazolin-4-amine (1 g). This hydroxy compound (350 mg) was mixed with DIPEA (350 muL) in DCM (10 ml) and cooled at 0 C, to the mixture was added MsCl (85 muL) and stirred for 2 hours. The reaction was evaporated with silica gel (2 g) and purified with silica gel column, then mixed with 5,8-Dioxa-10-azadispiro[2.0.4.3]undecane (B) (120 mg) and DIPEA (120 muL) in 2-propanol (10 ml). The reaction was refluxed overnight and evaporated then purified with silica gel column to give the titled product. Mass: (M+1), 515
With oxalyl dichloride; N-ethyl-N,N-diisopropylamine; In chloroform; at 60 - 65℃; for 12.0h; Oxalylchloride (62.9 g, 0.496 mol) was added to a mixture of <strong>[286371-64-0]6-benzyloxy-7-methoxyquinazolin-4(3H)-one</strong> 9 (40 g, 0.1416 mol) and diisopropyl ethyl amine (21 g, 0.1625 mol) in chloroform 200 mL. The reaction was maintained at 60-65C for 12 hr. The solvent was completely removed by vacuum distillation. A solution of 3-chloro-4-fluoroaniline (28.7 g, 0.1982 mol) in isopropanol 480 mL was added to the reaction mass at 25-30C. The reaction mass was heated up to 60-65C followed by slow addition of diisopropylamine (21 g, 0.1625 mol) and maintaining for 2 hr. The mixture was cooled to 0-5C for a period of 1 hr. The solid was collected by filtration, washed with chilled isopropanol and dried to get the light yellow compound 11 (54 g, 93%), purity 98-99% m.p. 258-60C; 1H NMR (Methanol-d4, 300 MHz): delta 8.183 (s, 1H), 8.005-8.036 (m, 1H), 7.709-7.761 (m, 1H), 7.556-7.602 (m, 2H), 7.378-7.531 (m, 5H), 7.321 (s, 1 H), 5.380 (s, 2H), 4.153 (s, 3H); MS (EI): m/z 411 (M + 1).

After cooling to room temperature, part of the solvent was removed in vacuo and ammonium hydroxide (5 mL, 30% in water) and water (50 mL) were added. The solid was filtered, was washed with water and hexanes, and was then dried under vacuum to afford 4.87 g (94% yield) of the title compound; MS (AP/CI): 283.1 (M+H)+ .
