Abstract
The present invention relates to a method for preparing piperidine derivative compounds by converting, with a piperidine compound, regioisomers having the formula: ##STR1## 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 ; R.sup.6 and R.sup.7 are the same or different and are selected from the group consisting of hydrogen, an alkyl moiety, an aryl moiety, OR.sup.8, SR.sup.8, and NR.sup.8 R.sup.9 ; X.sup.3 is halogen, OR.sup.15, SR.sup.15, NR.sup.15 R.sup.16, OSO.sub.2 R.sup.15, or NHSO.sub.2 R.sup.15 ; R.sup.5, R.sup.8, R.sup.9, R.sup.15, and R.sup.16 are the same or different and are selected from the group consisting of hydrogen, an alkyl moiety, and an aryl moiety; and A is a substituent of its ring and is selected from the group consisting of hydrogen, halogens, alkyl, hydroxy, alkoxy, and other substituents.
