To a solution of 5-(chloromethyl)-1-[3-(trifluoromethyl)phenyl]-1H-tetrazole (200 mg, 0.762 mmol, commercially available from Otava, Kiev, Ukraine) in acetonitrile (3 mL) was added triethylamine (0.318 mL, 2.285 mmol) and 3-methyl-2-piperazinone (87 mg, 0.762 mmol, Sigma-Aldrich). The reaction mixture was heated to 120° C. for 20 min in a microwave reactor. The reaction mixture was concentrated in vacuo. The crude product was purified by silica chromatography (Biotage SP4), eluting with an increasing gradient of (2N NH3 in MeOH) in DCM. The relevant fractions were combined and concentrate to give the title compound as white crystals (151 mg)
