85% | With dimethylsulfone; at 150℃; for 2h; | 3,5-dichlorophenyl-2-amino-4-oxo-3,4-dihydroquinazoline-6-carboxylate (or 2-Amino-4- oxo-3,4-dihydro-quinazoline-6-carboxylic acid methyl ester): The diester 4-Amino- isophthalic acid dimethyl ester (2.4 g, 0.011 mol) was added to a mixture containing dimethyl sulfone (12 g) and chloroformamidine hydrochloride (2.64 g 0.022 mol). The reaction content was heated at 150 0C for 2h and cooled to RT. The solid mass was added with water (50 ml) and stirred for 30 min. On adding aqueous ammonia to this suspension, the solid was precipitated out and filtered off. The solid was washed with water and dried to obtain 5 as off- white solid. Yield: 85 % (2.1 g) |
