실험 절차

A solution of the product of example 82A (2.05 g, 10.8 mmol) in methanol (30 mL) was stirred with potassium carbonate (1.49 g, 10.8 mmol) at room temperature. After 2 hours, the reaction mixture was filtered, and the filtrate was concentrated under vacuum to provide the title compound suitable for use in the next step: 1H NMR (300 MHz, methanol-d4) δ ppm 2.69 (s, 3H), 3.34 (s, 1H), 8.75 (s, 2H); MS (ESI) m/z 119 (M+H)+.
