実験手順
To a suspension of (S)-tert-butyl 2-(3′-chlorobiphenyl-4-yl)-1-(1-(2-cyanoethyl)-1H-tetrazol-5-yl)ethylcarbamate (300 mg, 0.662 mmol) in DCM (3 ml) at room temperature was added DBU (2 ml, 13.27 mmol), and the solution was stirred at room temperature for 1.5 hours. The reaction mixture was concentrated reduced pressure. The obtained residue was purified by reverse phase HPLC [30 to 95% ACN-water (0.1% TFA) over 10 min by Sunfire C18 column] and gave the title compound: 250 mg (yield: 94%). LCMS (condition F): 400.1 (M+1); retention time=1.28 min.
