1-(1-(Hetero)aryl)-1-(polyhydroxyalkyl)-methyl)-4-(4-(N-methylbenzamid o)-3-phenylbutyl)-piperazine derivatives (I) are new. Also new are 1-unsubstituted analog intermediates (II). 1-(1-(Hetero)aryl)-1-(polyhydroxyalkyl)-methyl)-4-(4-(N-methylbenzamid o)-3-phenylbutyl)-piperazine derivatives of formula (I) and their acid addition salts are new. A = naphthyl, phenyl (optionally substituted by OH), mono- or bi-cyclic heteroaryl or 3-6C alkenyl (optionally substituted by phenyl); Q = (CHOR1)k-(CHOR2)l-(CHOR3)m-(CHOR4)n-CH2OR5 ; R1-R5 = H or lower alkanoyl, or two of R1-R5 = CO, CS or CH2 (optionally substituted by lower alkyl or 4-5C alkylene), completing a 5- or 6-membered ring; k, l, m, n = 0 or 1, and R6, R7 = H or halo. Independent claims are also included for: (1) the preparation of (I), and (2) new piperazine derivative intermediates of formula (II). |
