Reaction Steps

Compound 17a (150 mg) was dissolved in methanol (35 ml) and ethyl acetate (35 ml). The obtained mixture was stirred for 30 minutes in a hydrogen atmosphere. After the reaction was over, the obtained reaction mixture was filtered through Cerite, and then washed with methanol. The solvent was distilled off from the filtrate, and the obtained residue was dried. Thus, Compound 20a (150 mg, quant.) was obtained as a white solid.
