実験手順

Silver trifluoromethanesulfonate (0.381 g, 1.483 mmol) was added portionwise to a solution of methyl (2R)-2-amino-5-[5-[{2-[3,5-bis(trifluoromethyl)phenyl]-2-methylpropanoyl}(methyl)amino]-4-(4-fluoro-2-methylphenyl)-2-pyridinyl]-4-pentynoate (Intermediate 13, 1.85 g, 2.97 mmol) in anhydrous Acetonitrile (25 ml) and the resulting reaction mixture was stirred at room temperature overnight. Volatiles were evaporated under vacuo at room temperature. The residue was taken-up in dichloromethane and filtered through a plug of celite to afford 2.2 g of the title compound as a brown solid (the material contained some residual acetonitrile, therefore overall recovered amount was higher than the theoretical amount).
