실험 절차
A mixture of [4-(5-cyclopropyl-3-methylpyridin-2-yl)piperazin-1-yl](6-fluoro-4-methylpyridin-3-yl)methanone (1.45 g) described in Preparation Example 140 and 4-methoxybenzylamine (1.12 g) was stirred at 100° C. for 5 hr. The reaction mixture was cooled, water was added, and the mixture was extracted with chloroform. The organic layer was washed with saturated brine, and the solvent was evaporated. The obtained residue was dissolved in dichloromethane (10 mL), trifluoroacetic acid (20 mL) was added, and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and the mixture was extracted with dichloromethane. The organic layer was washed with saturated brine, and the solvent was evaporated. The obtained residue was purified by column chromatography (hexane:ethyl acetate) to give the title compound (1.07 g).
