実験手順

To a solution of methyl 4-(4-biphenylylcarbonylamino)benzoate (1.998 g) in THF (60 ml)/methanol (20 ml) was added 1N aqueous sodium hydroxide (8 ml) and stirring was continued at room temperature for 18 hr. The reaction mixture was diluted with 1 N hydrochloric acid (10 ml) and extracted with ethyl acetate. The organic layer was washed with water and saturated aqueous sodium chloride sequentially, dried, and concentrated. The resulting crude crystals were washed with diethyl ether to obtain the titled compound (1.760 g).
