実験手順

To a solution of 1-(2-(benzyloxy)-2-oxoethyl)cyclopentanecarboxylic acid (49.4 mg, 0.188 mmol) and (R)-3-(5-(1-amino-2-(biphenyl-4-yl)ethyl)-1H-tetrazol-1-yl)propanenitrile (50 mg, 0.157 mmol) in DMF (1.5 mL) were added EDC.HCl (36 mg, 0.188 mmol), HOAt (26 mg, 0.188 mmol) and triethylamine (0.033 mL, 0.236 mmol). After being stirred for 2 hours, the reaction mixture was diluted with EtOAc. The mixture was washed with H2O2O and brine, dried over Na2SO4 and concentrated. The residue was purified by silica gel flash column chromatography (eluent; EtOAc/heptane) to give (R)-benzyl 2-(1-(2-(biphenyl-4-yl)-1-(1-(2-cyanoethyl)-1H-tetrazol-5-yl)ethylcarbamoyl)cyclopentyl)acetate (39 mg). LCMS (condition A) δ 563 (M+1); retention time=1.85 min.
