実験手順

A mixture of compound 7B (15 mg, 0.044 mmol), ethanesulfonyl chloride (5 μL, 1.5 eq), triethylamine (15 μL, 3.0 eq) and dichloromethane (1 mL) was stirred at room temperature overnight. The clear solution was directly loaded on silica gel column and eluted with 0.5% ammonium hydroxide and 5% methanol in dichloromethane to give the desired product (12.5 mg, 82% yield)

後処理
