反応手順
19 g of 4-benzyl-2-(1-phenyl-2,3-dihydro-imidazo(4,5-b)pyridin-2-on-3-yl-methyl)-morpholine hydrochloride are treated in accordance with part (a) of Example 2. The oil obtained is dissolved in hot isopropanol. A hot solution of maleic acid in isopropanol is added. The salt precipitates slowly. Recrystallization from isopropanol gives 5 g of 2-(1-phenyl-2,3-dihydro-imidazo-(4,5-b)pyridin-2-on-3-yl-methyl)-morpholine maleate, m.p. 190° C.
