실험 절차

To methyl 4-bromo-2-(1,1-dioxoisothiazolidin-2-yl)benzoate (2 g) described in Preparation Example 116 were added 1N aqueous sodium hydroxide solution (9 mL) and methanol (18 mL), and the mixture was stirred at 60-70° C. 1N hydrochloric acid (9 mL) was added, a solution of 1-(3,5-dimethylpyridin-2-yl)piperazine (1.14 g) described in Preparation Example 47 in methanol (2 mL) and 4-(4,6-dimethoxy[1.3.5]triazin-2-yl)-4-methylmorpholinium chloride hydrate (DMT-MM) (1.65 g) were added, and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. After evaporation of the solvent, the residue was purified by column chromatography (hexane:ethyl acetate) to give the title compound (2.4 g).
