Procedimiento

To a solution of 27.7 gm (0.39 mole) ethyl isocyanate in 250 mL chloroform were added 50 gm (0.39 mole) 3-(1-pyrrolidinyl)propylamine dropwise with cooling. Once the addition was complete, the cooling bath was removed and the reaction mixture stirred at room temperature for 4 hours. The reaction mixture was then concentrated under reduced pressure to give 74.5 gm (96.4%) of the desired urea as a clear oil.
