反应详情

The title compound from example 32.1 (600 mg, 2.7 mmol) was dissolved in a solution of sodium hydroxide (216 mg, 5.4 mmol) and water (5 mL). When a clear, uniform solution was observed ethanol (6 mL) was added, followed by iodomethane (268 μL, 4.3 mmol). The reaction was stirred at room temperature for 6 h. The reaction mixture was then diluted with water and extracted four times with chloroform. The organic phase was dried over magnesium sulfate, filtered and concentrated to yield the title compound (yellowish solid, 500 mg, 78%).
