Abstract

1411783 Piperidine derivatives JOHN WYETH & BRO Ltd 22 Feb 1973 [24 Feb 1972] 10427/75 Divided out of 1411782 Heading C2C The invention comprises piperidine derivatives of the formula wherein R<SP>1</SP> is C 1-6 alkyl or C 3-6 cycloalkyl, R<SP>2</SP> is H OH, C 1-6 alkyl, C 1-6 alkoxy or C 3-6 cycloalkyl, R<SP>3</SP> is H or C 1-6 alkyl, W is an optionally substituted phenyl and A is C 1-4 , alkylene and acid addition and quaternary ammonium salts and their preparation. The 4-phenyliminopiperidines of Formula V are prepared by condensing the corresponding 4-piperidones with the appropriate anilines. The 4-anilinopiperidines of Formula IV in which R<SP>3</SP> is H are prepared by reducing the corresponding compounds of Formula V, and those in which R<SP>3</SP> is H or C 1-6 alkyl by treating the appropriate quaternary ammonium salts under mild conditions such as to remove the quaternizing group or by hydrolysing compound of the formula wherein R is C 1-6 alkyl, C 1-6 alkoxy, di(C 1-6 alkyl)amino, 1 - pyrrolidinyl, morpholino or piperidino.
