    • The present invention discloses processes for preparing piperidine derivative compounds of formulae (I) or (II) wherein n is 0 or 1; R is hydrogen or hydroxy; R is hydrogen; or, when n is 0, R and R taken together form a second bond between the carbon atoms bearing R and R , provided that when n is 1, R and R are each hydrogen; R is -COOH or -COOR ; R is an alkyl or aryl moiety; A, B, and D are the substituents of their rings, each of which may be different or the same, and are selected from the group consisting of hydrogen, halogens, alkyl, hydroxy, alkoxy, and other substituents. One process comprises providing a regioisomer of formula (III) wherein Z is -CG G G , (IV) or (V), 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 ; G , G , and G are the same or different and are selected from the group consisting of OR , SR , and NR R ; X is halogen, OR , SR , NR R , OSO2R , or NHSO2R ; R and R are the same or different and are selected from the group consisting of hydrogen, an alkyl moiety, an aryl moiety, OR , SR , and NR R ; and R , R , R , R , and R are the same or different and are selected from the group consisting of hydrogen, an alkyl moiety, and an aryl moiety; and converting the regioisomer to the piperidine derivative compound with a piperidine compound. Another process for producing piperidine derivative compounds comprises providing an alpha , alpha -disubstituted-methylbenzene derivative having formula (VI) wherein X is a halogen, trialkyl or triaryl tin, trialkyl or triaryl borate, trialkyl silicon, alkylhalo silicon, a substituted sulfonic ester, or substituents useful in organometallic coupling reactions and converting the alpha , alpha -disubstituted-methylbenzene derivative to the piperidine derivative compound with a piperidine compound. In yet another process, a 4-( alpha , alpha -disubstituted)-toluic acid derivative having formula (VII) wherein X is a halogen; an alkali metal oxide; a moiety having formula -OR ; a moiety having formula -SR ; or an amine; and R is selected from the group consisting of hydrogen, an alkyl moiety, and an aryl moiety, is provided and converted to the piperidine derivative compound with a piperidine compound.
