4-(1,1-Dioxo-1λ6-isothiazolidin-2-yl)-3-methoxybenzoic acid (285 mg) described in Preparation Example 21 and 1-(2,4-dimethylphenyl)piperazine (199 mg) were dissolved in a solution of chloroform (2.1 mL) and methanol (2.1 mL), 4-(4,6-dimethoxy[1.3.5]triazin-2-yl)-4-methylmorpholinium chloride hydrate (349 mg) was added, and the mixture was stirred at room temperature. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and the solvent was evaporated. The obtained residue was purified by column chromatography (chloroform:methanol) to give the title compound (411 mg).
