실험 절차
A stirred solution of the intermediate from Step A (6.5 g, 23.7 mmol) in MeOH (300 mL) was flushed with nitrogen gas and palladium (650 mg; 10 wt. % (dry basis) on activated carbon) was added. The reaction flask was then placed under vacuum and flushed with hydrogen gas (3 cycles). The reaction mixture was stirred overnight (16 hours) and then flushed with nitrogen gas. The mixture was filtered and the solvent removed under reduced pressure to provide 6.2 g of the title intermediate (94% yield), which was used without further purification.
