反应详情

To a solution of Intermediate 54 (1.4 g, 4.37 mmol) in methanol (50 mL) was added palladium on charcoal (10%, 0.143 g). The reaction mixture was hydrogenated under a balloon pressure at room temperature overnight. The catalyst was filtered through Celite® and the solvent removed under reduced pressure to give the title compound as a solid, which was used in the next step without further purification. MS (M+): 238.
