YieldReaction ConditionsOperation in experiment
75% 60% Sodium hydride dispersion (0.11 g, 2.7 mmol) was added portionwise to DMSO (3 mL)at 22"C under nitrogen. The resulting slurry was stirred at ambient temperature for 5 minutes.5 4-Amino-3-methoxyphenol (0.37 g, 2.7 mmol) was added to the mixture at 22 - 28C undernitrogen and the resulting grey slurry was stirred at ambient temperature for 5 minutes. 4-Chloro-6,7-dimethoxyquinazoline (0.5 g, 2.2 mmol) was added to the mixture at 22 - 28Cunder nitrogen. The resulting dark mixture was stirred at 60C for 30 minutes then at ambienttemperature for 3 hours. Water (40 mL) was added to the mixture. The resulting precipitate10 was collected by filtration and washed with water (2 x 10 mL). The solid was treated withmethanol (5 mL) and evaporated to afford the title compound as a grey solid (0.54 g, 75%),which was used without further purification. 1H NMR (500 MHz, DMSO, 27 oq 8 3.74 (3H,s), 3.96 (6H, d), 4.67 (2H, s), 6.59 (lH, dd), 6.67 (lH, d), 6.76 (lH, d), 7.35 (lH, s), 7.51 (lH,s), 8.51 (lH, s). m/z: ES+ [M+H]+ 328.
72% With dimethyl sulfoxide; In methanol; water; Production Example 5: 4-[(6,7-Dimethoxy-4-quinazolinyl)oxy]-2-methoxyaniline Sodium hydride (60 wt%, 3.2 g) was added to dimethyl sulfoxide (50 ml), and the mixture was stirredat 50C for 20 min. 4-Amino-3-methoxyphenol (5.6 g) was added thereto, and the mixture was stirred at room temperature for 10 min. Next, <strong>[13790-39-1]4-chloro-6,7-dimethoxyquinazoline</strong> (7.0 g) was added thereto, and the mixture was stirred at 100C overnight. Water was added to the reaction solution, and the mixture was extracted with chloroform. The chloroform layer was then washed with a saturated aqueous sodium hydrogencarbonate solution and was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure. Methanol was added to the residue, and the precipitated crystal was collected by suction filtration to give the title compound (7.3 g, yield 72%). Mass spectrometry value (ESI-MS, m/z): 328 (M++1)
