N-Acylpyrrolidine derivs. of formula (I) are new. (where R1-R3 = H, halo, alkyl or aryl; R4 = H, halo, CN, alkyl, aryl or alkoxycarbonyl; R5 = H, alkyl or aryl; R6 = alkyl or aryl; X = H, halo or alkyl; m = 1-3). - Specifically R1-R3 = H, F, Cl, Br or opt. substd. 1-6C alkyl or 6-10C aryl; R4 = H, F, Cl, Br, CN, 1-6C alkoxy-carbonyl, or opt substd. 1-6C alkyl or 6-10C aryl; R5 = H or opt. substd. 1-6C alkyl or 6-10C aryl; R6 = 1-6C alkyl or 6-10C aryl, both opt. substd.; x = H, F, Cl, Br or opt. substd. 1-4C alkyl; m = 1, 2 or 3; Alkyl substits. are F, Cl, Br, OH, MeO or EtO; Aryl substits. are F, Cl, Br, 1-4C alkyl or 1-4C alkoxy. |
