PROCESS FOR PRODUCING 4-ARYLPIPERIDINE-3-CARBINOLS AND RELATED COMPOUNDS

摘要

Aryl-2-piperidones of formula (7) can be reduced to form aryl-piperidine carbinols of formula (1), which are useful in forming a variety of pharmaceutical compounds including paroxetine, in good yield and purity. Related compounds and synthesis schemes are also set forth. In said formulas, X represents a hydrogen atom, a halogen atom, a lower alkyl group, an aralkyl group, an alkoxy group, a dialkylamino group or an alkylthio group; R represents a hydrogen atom, a lower alkyl group, an aryl group, an aralkyl group, an alkoxycarbonyl group, aralkoxycarbonyl group or an aryloxycarbonyl group; and R<1> represents a hydrogen atom, a lower alkyl group, an aryl group or an aralkyl group.
