Versuchsvorschrift

The condensation of 0.1 mol of 1-isopropenyl-2,3-dihydro-benzimidazol-2-one and 0.1 mol of 2-chloromethyl-4-benzyl-morpholine in accordance with the procedure (a) of Example 1 gives, after evaporation of the solvent under reduced pressure, 30 g of an oil which solidifies slowly. Recrystallization from a 250/25 mixture of isopropyl ether and isopropanol gives 26.5 g of 4-benzyl-2-(1-isopropenyl-2,3-dihydro-benzimidazol-2-on-3-yl-methyl)-morpholine, m.p. 117° C.
