실험 절차

Using (6-bromopyridin-3-yl)[4-(3,5-dimethylpyridin-2-yl)piperazin-1-yl]methanone (150 mg) described in Preparation Example 127 and 1-(4-methoxybenzyl)-4-methylimidazolidin-2-one (106 mg) described in Preparation Example 52 and by the reaction and treatment in the same manner as in Example 1, 3-{5-[4-(3,5-dimethylpyridin-2-yl)piperazine-1-carbonyl]pyridin-2-yl}-1-(4-methoxybenzyl)-4-methylimidazolidin-2-one (132 mg) was obtained. The obtained 3-{5-[4-(3,5-dimethylpyridin-2-yl)piperazine-1-carbonyl]pyridin-2-yl}-1-(4-methoxybenzyl)-4-methylimidazolidin-2-one (132 mg) was dissolved in trifluoroacetic acid (2 mL), trifluoromethanesulfonic acid (0.11 mL) was added, and the mixture was stirred at room temperature for 30 min. To the reaction mixture was added 5% aqueous sodium hydrogen carbonate solution, and the solvent was evaporated, and the mixture was extracted with ethyl acetate. The organic layer was washed with 5% aqueous sodium hydrogen carbonate solution and saturated brine, and the solvent was evaporated. The obtained residue was purified by silica gel column chromatography (ethyl acetate:methanol) to give the title compound (83 mg).
