Participants

Reaction Steps

The condensation of 0.1 mol of 1-phenyl-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, a pale pink solid which melts at about 90° C. and which is used as such for the subsequent operations.
