25 °C

A mixture of 3.1 g of 5-(bromomethyl)-1,3-dihydro-4-(4-methoxybenzoyl)-2H-imidazol-2-one, 12 ml of 30% aqueous dimethylamine and 24 ml of ethanol is stirred at 25° C. for 2 hours. The solvent is then evaporated from the mixture under reduced pressure and the resultant residue is recrystallized twice from ethanol to give 4-[(dimethylamino)methyl]-1,3-dihydro-5-(4-methoxybenzoyl)-2H-imidazol-2-one melting at about 165°-167° C. with decomposition.
