Procedure

0.8 ml of 5.35 N sodium methoxide is added to a suspension of 10 g (0.062 mol) of N-phenyl-N′-propargylurea in 140 ml of toluene. The mixture is heated at the reflux temperature for 4 hours. The solvent is evaporated and then the solid residue is taken up in acetone. The product precipitates, it is filtered, washed with a small amount of acetone and dried under vacuum at 50° C. 6 g of product are obtained. (m.p.=207° C.).
