実験手順

To the solution of 131 (3.27, 10 mmol) in anhydrous NMP (3.6 mL) under nitrogen is added urea (1.60 g, 26 mmol). The resulting mixture is heated to 160° C. and stirred for 6 hours. On cooling, the reaction mixture is poured into water (80 mL), pH is adjusted to 7 with hydrochloric acid, and the solution is extracted with dichloromethane (50 ml×4). The organic solution is dried with anhydrous sodium sulfate and concentrated to give the crude product 177 as an oil which is used directly in the next step reaction.
