Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Alternatively, the urea of this example was prepared as follows: A mixture of 26.5 g (0.3 mol) of 1,2-diamino-2-methylpropane, and 18 g (0.3 mol) of urea in 150 ml of water was refluxed for 4 hours. The mixture was evaporated in vacuo. The residue was dissolved in chloroform, filtered and evaporated to form a solid which was recrystallized in ethyl acetate to give 15 g of product (38%), m.p. 87°-90° C. The NMR and IR spectra were consistent with the assigned structre. was refluxed for 4 hours The mixture was evaporated in vacuo The residue was dissolved in chloroform filtered evaporated to form a solid which was recrystallized in ethyl acetate
