Procedure

Compound 1 (1.0 g), 5% Pd—C (131 mg) were suspended in methanol (60 mL). Evacuation and replacement with hydrogen were repeated three times. Subsequently, the suspension was vigorously stirred at room temperature (20 to 30° C.) for 8 hours under hydrogen atmosphere. After the reaction was completed, the mixture was filtered through Celite and the filtered product was washed with methanol. The filtrate was evaporated under reduced pressure to give 853 mg of a crude desired product of Compound 3 as a yellow solid.
