YieldReaction ConditionsOperation in experiment
67% 1) A mixture (about 3:1, 52.0 g; described in Leonard et al., J. Org. Chem. 1975, 40, 356-363) of 7-chloro-6-nitro-3H-quinazolin-4-one and 7-chloro-8-nitro-3H-quinazolin-4-one and DMF (0.7 mL) were added to thionyl chloride (200 mL) and the mixture was heated under reflux for 4 hrs. The reaction mixture was concentrated to dryness and toluene (150 mL) was added. The mixture was concentrated further. This step was repeated twice and dichloromethane (280 mL) was added to the residue. The mixture was stirred at room temperature. To this suspension was added dropwise a solution (760 mL) of 3-chloro-4-fluoroaniline (36.9 g, 253.6 mmol) in isopropanol. Dichloromethane (300 mL) was added and the mixture was stirred, at 20 C. for 20 min. Hexane (600 mL) was added under ice-cooling, and stirring was continued at 20 C. The precipitate was collected by filtration, washed with hexane (200 mL×2) and dried under reduced pressure. The obtained solid was added to methanol (1 L)-water (120 mL), and triethylamine (30 mL) was added with stirring under ice-cooling. After stirring at room temperature for 1 hr, the precipitate was collected by filtration and washed with water (700 mL×2). The crudely purified substance (65 g) was suspension-washed with acetonitrile (1.2 L) with heating, and collected by filtration to give the objective (7-chloro-6-nitro-4-quinazolinyl)-(3-chloro-4-fluorophenyl)amine (54.6 g, 67%).

YieldReaction ConditionsOperation in experiment
98% To a 250 mL four-necked flask was added 2.3 g (10.2 mmol)7-chloro-6-nitroquinazolin-4-one (7), 3 to 4 drops of DMF and 10 mL of thionyl chloride,Stirring to reflux, 30min after the solid completely dissolved, reflux reaction 2.5h,Sulfur disulfide was evaporated to give a pale yellow solid.To the reaction flask was added 1.8 g (12.2 mmol)3-chloro-4-fluoroaniline and 1,4-dioxane solution 25mL,Added, the reaction was yellow turbid liquid, slowly warming to 90 ,And reacted at that temperature for 1 h. After cooling to room temperature, pour into the water,Precipitation of light orange solid, with saturated aqueous sodium bicarbonate solution to neutral,Filtered, washed with water and dried to give 3.5 g of an orange solid, 98% yield,Purity 96%.
70% The phosphorus oxychloride (phosphorous oxy chloride) 10 ml melting was dissolved in 7- chloro- 6- nitro quinazoline - 4 (3H) -one 11 (5 g, 22.16 mmol) which were the starting material in the CH 3 CN of 30 ml was added and the mixture was stirred at 80 for 5 hours. After 5 hours, 3-chloro-4-fluoroaniline (3.871 g, 26.59 mmol) dissolved in 10 ml of dioxane was added dropwise thereto, followed by stirring for 1 hour. After the completion of the reaction was confirmed by TLC, the pH of the solution was adjusted to between 8 and 10 with 2N KOH solution, and the resulting solid was filtered. The solid compound was washed with water and ethanol, and then Compound 12 (6.574 g, 18.61 mmol , 70%) was obtained
