Participants

Reaction Steps

A mixed solution of ethyl (2E)-3-(3-(5-((3,3-dimethylbutanoyl)amino)-4,6,7-trimethyl-2,3-dihydro-1-benzofuran-3-yl)phenyl)acrylate (400 mg, 0.89 mmol) obtained in Example 177 and 10% palladium on carbon (water content: 50%, 40 mg) in ethanol (3 mL)-ethyl acetate (5 mL) was stirred at room temperature for 2 hours under a hydrogen atmosphere. The reaction solution was filtered through celite and the filtrate was concentrated under reduced pressure to obtain 326 mg (yield: 81%) of the title compound. Melting point: 136-138° C. (ethyl acetate-hexane).
