Reaction Steps
To a solution of 5-(chloromethyl)-1-[4-(trifluoromethyl)phenyl]-1H-tetrazole (500 mg, 1.90 mmol, commercially available from UkrOrgSynthesis, Kiev, Ukraine) in acetonitrile (8 mL) was added triethylamine (0.796 mL, 5.71 mmol) and (3S)-3-methyl-2-piperazinone (239 mg, 2.09 mmol, commercially available, for example from Sigma Aldrich, St Louis, USA). The reaction mixture was heated to 120° C. for 20 min. The reaction mixture was concentrated in vacuo and the crude product purified by reverse phase chromatography (Biotage SP4). The relevant fractions were combined, concentrated and dried in vacuo to yield the title compound as white crystals (349 mg).
