PROCEDURE

实验过程

18 g of 4-benzyl-2-(1-phenyl-2,3-dihydro-benzimidazol-2-on-3-yl-methyl)-morpholine are treated as in part (a) of Example 2. After evaporation of the solvent under reduced pressure, 15 g of an oily product are obtained and are dissolved in hot isopropyl alcohol. A hot solution of maleic acid in isopropanol is added. The salt precipitates slowly. 16.5 g of 2-(1-phenyl-2,3-dihydro-benzimidazol-2-on-3-yl-methyl)-morpholine maleate are obtained, m.p. 200° C.
