Reaction Steps

To a solution of (2R)-1-acetoxy-2-acetylamino-2-methyl-4-[1-methyl-5-(5-phenylpent-1-ynyl)pyrrol-2-yl]butane (77 mg, 0.19 mmol) obtained in Example (31a) in methanol (2 ml) was added 10% palladium-charcoal (50% wet with water) (4.3 mg), and the resulting mixture was stirred at room temperature under a hydrogen atmosphere for 1 hour. After stirring, the internal atmosphere was replaced with nitrogen, and the palladium-charcoal in the reaction mixture was filtered off using celite, which was washed with ethyl acetate. The filtrate and the washings were combined and evaporated to dryness in vacuo to afford the title compound (75.5 mg, yield: 97%).
