実験手順

A mixture of lithium hydroxide (107 mg, 4.48 mmol), (R)-ethyl 4-(4-((4′-chlorobiphenyl-2-yl)(dimethoxyphosphoryloxy)methyl)piperidin-1-yl)benzoate (INTERMEDIATE 121, 500 mg, 0.9 mmol), THF (10 ml), water (2.5 ml), and MeOH (2.5 ml) was heated at 35° C. overnight. The reaction mixture was concentrated under reduced pressure, diluted with water (10 ml) and acidified with an aqueous solution of 6 N HCl, resulting in a precipitate. The solid was collected by filtration to give the title compound (270 mg, yield: 57%). The title compound was used in the preparation of EXAMPLE 30 without further purification.
