Synthesis of substituted 1-aralkyl-1H-v-triazoles

A process of preparing compounds represented by formulas ##STR9## comprising:

• (a) reacting a compound represented by the formula ##STR10## with an alkylating agent in the presence of a base and a solvent to produce a product containing at least one compound represented by the formulas ##STR11## PG,23 (b) separating the product of step (a) into the individual compounds prepared in step (a);
• (c) reacting a compound represented by formulas (5) or (6) with an oxidizing agent to produce a product represented by the following formulas (7) and (8) ##STR12## respectively;
• and (d) decarboxylating the product of step (c) by heating to form compounds represented by formulas (1) and (2), wherein A together with the carbon atom shown form a phenyl radical;
• R', R" and R''' each independently represent a lower alkyl radical having 1 to 6 carbon atoms, a phenylalkyl radical having 7 to 12 carbon atoms, a mono-, di- or tri-lower alkoxy (C.sub.1 to C.sub.4) substituted phenylalkyl radical having 7 to 12 carbon atoms where the substitution is on the phenyl ring, a mono-, di- or tri-halogen substituted phenylalkyl radical having 7 to 12 carbon atoms where the substitution is on the phenyl ring, or a mono-, di- or tri-nitro substituted phenylalkyl having 7 to 12 carbon atoms where the substitution is on the phenyl ring and R''' also represents a hydrogen atom;
• X represents a halogen atom, lower alkoxy radical having 1 to 4 carbon atoms or a nitro radical, and n is 0 or 1.
