Procedure

To a solution of 5-(chloromethyl)-1-[3-(trifluoromethyl)phenyl]-1H-tetrazole (440 mg, 1.68 mmol, commercially available from Otava, Kiev, Ukraine) in acetonitrile (8 mL) was added 1,1-dimethylethyl 2,2-dimethyl-1-piperazinecarboxylate (359 mg, 1.68 mmol, commercially available, for example from ChemPacific Corp., Baltimore, USA) and triethylamine (0.701 mL, 5.03 mmol). The mixture was then heated to 120° C. for 20 minutes in a microwave reactor.
