Application
A Condensing Agent
Experimental procedure: at 0 °C NMM (23.9 mL, 212 mmol) is added to 1 (43.5 g, 193 mmol) and TPTU (73.9 g, 244 mmol) in dichloromethane (720 mL), followed by 2 (28 mL, 212 mmol) in dichloromethane (80 mL). The solution is stirred for 2 h at 0 °C and warmed to room temperature overnight. Additional 2 (5 mL, 39 mmol) is added and stirring is continued for 4 h. The solution is poured on ice water, the layers are separated, and the aqueous layer is extracted with dichloromethane. The combined organic layers are washed with water, dried over MgSO4, filtered, and evaporated. Flash chromatography on silica gel (hexane:ethyl acetate = 4:1 ~ 1:1) yields 3 (64.8 g, 94%) as a light yellow oil.
