Reaction Steps

A solution of 2-[7-chloro-6-(cyanomethyl)-2-oxo-4-phenyl-2H-chromen-3-yl]-N-(4-chloro-2-trifluoromethylphenyl)acetamide (100 mg) in THF (5 ml) was combined with Raney-cobalt (100 mg), and stirred under hydrogen atmosphere (4.5 atm) at room temperature for 7 hours. After the catalyst was filtered off, the filtrate was concentrated under reduced pressure to obtain the residue, which was recrystallized from ethyl acetate to obtain the title compound (27 mg, yield: 27%). Melting point: 165-167° C.
