実験手順
To oxalyl chloride (0.124 mL, 2.0M in dichloromethane) in dichloromethane (2 mL) at −78° C. was added dimethylsulfoxide (0.035 mL) in dichloromethane (0.2 mL). The mixture was stirred for 10 min and the product from Step D (69 mg) was added as a solution in dichloromethane (2 mL). The reaction mixture was stirred for 30 min at −78° C. and triethylamine (17 mL) was added rapidly. After 30 min, the −78° C. bath was removed and the reaction warmed to ambient temperature over 30 min at which point the reaction was quenched with saturated aqueous sodium bicarbonate solution (5 mL) The phases were separated and the aqueous phase extracted with dichloromethane (3×10 mL). The combined organic phases were dried over anhydrous sodium sulfate, filtered, evaporated in vacuo and used without further purification. LC/MS 278.2 (M+1).
