Participants

Reaction Steps

Under an argon atmosphere, to a 500-mL pear-shaped evaporating flask was added the compound prepared in Example 5 (53.6 g) to which a mixed solution of methanol (50 mL) and ethyl acetate (175 mL) was added. The mixture was heated until dissolution, and the flask was purged with argon prior to addition of 5% palladium carbon (10.8 g). The flask was degassed and charged with hydrogen gas. The flask was vigorously stirred at room temperature for 3 hours. The reaction system was purged with argon, filtered with celite and washed with ethyl acetate. The obtained filtrate was subjected to distillation under reduced pressure to give the titled compound (43.9 g) having the following physical properties.
