Procedure

Iodomethane (80 mg, 0.84 mmol) was added to a mixture of (E)-ethyl 3-(4-((E)-2-cyclobutyl-1-(1H-indazol-5-yl)-2-phenylvinyl)phenyl)acrylate (0.25 g, 0.56 mmol; intermediate in the preparation of Compound 84), K2CO3 (0.12 g, 0.84 mmol), and DMF (5.6 mL) at room temperature. The resulting mixture was stirred overnight, diluted with water, and extracted with EtOAc. The extract was washed with water, washed with brine, dried over sodium sulfate, filtered, concentrated, and then purified on a silica gel column using 0-50% EtOAc in hexanes to afford the title compound. LCMS: 463 (M+H)+.
