At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-Amino-4-methylbenzonitrile, and friends who are interested can also refer to it.
Adding a certain compound to certain chemical reactions, such as: 60710-80-7, name is 3-Amino-4-methylbenzonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 60710-80-7, category: nitriles-buliding-blocks
To a solution of 2-chloro-4-phenylquinazoline (9.6 g, 40 mmol) in 2-propanol (130 mL) was added 4-aminobenzoic acid (8.2 g, 60 mmol) and the mixture was stirred at reflux for 4 h. The mixture was cooled to it and the precipitate was collected by filtration and washed with 2-propanol. The product, 4-(4-phenylquinazolin-2-ylamino)benzoic acid, was isolated as a yellow solid (12.9 g, 95 %).[00337] To a stirred mixture of 4-(4-phenylquinazolin-2-ylamino)benzoic acid (1.37 g, 4.02 mmol), 3-amino-4-methylbenzonitrile (529 mg, 4.01 mmol), and Hunig’s base (2.1 mL, 12 mmol) in dimethyl formamide (10 mL) was added HATU (3.04 g, 8.00 mmol). Thestirred mixture was heated to 80 0C overnight, then cooled to rt. The reaction was diluted with ethyl acetate and extracted with water. The organic layer was washed with saturated sodium bicarbonate and concentrated on a rotary evaporator. The residue was sonicated with acetonitrile and filtered to give a light yellow solid, which was again washed with water, acetonitrile, and dried under reduced pressure to give jV-(5-cyano-2-methylphenyl)-4-[(4- phenylquinazolin-2-yl)amino]benzamide (1.18 g, 65%) as a light yellow solid. 1H NMR (400 MHz, DMSOd6): delta 10.36 (s, IH), 9.87 (s, IH), 8.19 (d, 2H), 8.00 (d, 2H), 7.91-7.78 (m, 6H), 7.66-7.62 (m, 4H), 7.51 (d, IH), 7.42 (ddd, IH), 2.36 (s, 3H). MS (EI) for C29H21N5O: 456.1 (MH+).
