Abstract
1,251,600. Quinazoline derivatives. SUMITOMO CHEMICAL CO. Ltd. 11 July, 1969 [18 July, 1968 (2); 18 Oct., 1968], No. 35151/69. Heading C2C. Compounds of the general formula (R=H, C 1-4 alkyl, C 2-4 alkenyl, aralkyl, C n H 2n Z; n = 1-4; Z = C 1-4 alkoxy, di-(C 1-4 alkyl)amino; R 1-3 = H, halogen, C 1-4 alkyl, alkoxy, alkylthio or alkylsulphonyl, N0 2 , CF 3 ) and their salts are prepared by reacting a compound of the formula (X 1-3 = halogen) with ammonia. The starting materials are prepared by acylating the parent 2-aminobenzophenone with the appropriate trihaloacetic acid or a derivative thereof.
