Procedure

Ten percent sodium hydroxide (0.650 g) was added to a mixture of 1-(2,4-dichlorobenzylamino)-6-(ethoxycarbonyl)-3-methyl-2-benzimidazolone (0.308 g), ethanol (4 ml), tetrahydrofuran (8 ml) and water (4 ml), and the mixture was stirred at 60° C. for 2.5 hr. A part of the reaction mixture was concentrated, and neutralized with a saturated aqueous solution of sodium hydrogencarbonate. The crystals precipitated were filtered and dried to give the objective compound (0.276 g).
