Reaction Steps

Using (6-bromo-4-methylpyridin-3-yl)[4-(3,5-dimethylpyridin-2-yl)piperazin-1-yl]methanone (195 mg) described in Preparation Example 228 and 1-methylimidazolidin-2-one (75 mg) and by the reaction and treatment in the same manner as in Example 511, 1-{5-[4-(3,5-dimethylpyridin-2-yl)piperazine-1-carbonyl]-4-methylpyridin-2-yl}-3-methylimidazolidin-2-one (160 mg) was obtained. The obtained 1-{5-[4-(3,5-dimethylpyridin-2-yl)piperazine-1-carbonyl]-4-methylpyridin-2-yl}-3-methylimidazolidin-2-one (160 mg) was dissolved in ethyl acetate, 4N hydrogen chloride/ethyl acetate (0.2 mL) was added, and the precipitate was collected by filtration to give the title compound (98 mg).
