Reaction Steps

Obtained from Intermediate 33 (0.365 g, 0.62 mmol) and palladium on charcoal (10%, 0.075 g) by the same procedure described in Example 1 (reaction time: 20 hours). The crude was purified by column chromatography with silica gel, eluting with methylen chloride/methanol/ammonium (40:2.5:0.1) and the title compound was obtained as a solid (0.113 g, 65%).
