New piperidine derivatives which have a useful pharmacological activity such as a hypotensive activity are disclosed. The novel compounds are of the formula
wherein A is hydroxy, halogen, lower alkyl, lower alkoxy, lower alkenyloxy, lower alkenyloxy, lower alkylthio, carboxy, lower alkoxycarbonyl, nitro, amino, lower alkylamino, lower alkanoylamino, sulfamoyl, mono- or di-lower alkylaminosulfonyl, lower alkylsulfonyl, carbamoyl, cyano or trifluoromethyl;
m is 0 or an integer of 1-5, and when m is 2 or more, the A groups may be the same of different and any two A's may together form a lower alkylenedioxy group;
X is oxygen, sulfur, carbonyl, hydroxymethylene or methylene;
R1 is straight-chain alkylene having 1-4 carbon atoms with or without lower alkyl substituent(s); R2 is hydrogen or lower alkyl; and
Y is a monovalent or divalent group of the formula 1,2 or 3:
wherein p and q are each 0 or 1 provided that p and q are not both 1 at the same time: and when p and q are both 0, B is -N=N-.
p is 1 and q is 0, B is -CONH-, -COO-,
and when
p is 0 and q is 1, B is -CONH or -S02NH-;
and R3 is hydroxy, lower alkoxy, halogen, trifluoromethyl, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, nitro or amino;
n is 0 or an integer of 1-4, and when n is 2 or more, the R3 groups may be the same or different and any two R3 groups maytogetherform a lower alkylenedioxv group;
wherein R3 and n are as defined above, and
wherein R3 and n are as defined above.
Also disclosed are acid addition salts of the above compounds, pharmaceutical compositions containing them and a method for their preparation.
