Reaction Steps

To a mixture of the compound (54 mg) obtained in Step 1 and ammonium formate (49 mg) in ethanol (2.0 ml) was added 10% palladium carbon (50 mg) at 80° C. After stirring at 80° C. for 30 min, ammonium formate (49 mg) and 10% palladium carbon (50 mg) were added. After stirring at 80° C. for 30 min, the reaction mixture was allowed to return to room temperature, and the reaction mixture was diluted with ethyl acetate. The mixture was filtered through celite, and the filtrate was concentrated under reduced pressure. The residue was purified by thin layer silica gel chromatography (ethyl acetate) to give the title compound (24 mg).
