Abstract
The present invention relates to a method for preparing piperidine derivative compounds by converting, with a piperidine compound, regioisomers having the formula: ##STR1## where Z is --CG.sup.1 G.sup.2 G.sup.3, ##STR2## and where m is an integer from 1 to 6; Q and Y are the same or different and are selected from the group consisting of O, S, and NR.sup.5 ; G.sup.1, G.sup.2, and G.sup.3 are the same or different and are selected from the group consisting of OR.sup.8, SR.sup.8, and NR.sup.8 R.sup.9 ; and R.sup.5, R.sup.8, and R.sup.9 are the same or different and are selected from the group consisting of hydrogen, an alkyl moiety, and an aryl moiety.
