실험 절차

4-t-Butyl-N-[6-(3-hydroxypropyloxy)-5-(2-methoxyphenoxy)-2-piperazinyl-4-pyrimidinyl]-benzenesulfonamide (80 mg; 0.14 mmol), WSC·HCl (61.6 mg; 0.28 mmol), N-hydroxybenzotriazole (75.6 mg; 0.56 mmol), and formic acid (6.5 mg; 0.15 mmol) were dissolved in dimethylformamide-methylene chloride (1:1, 1 ml). The mixture was stirred overnight at room temperature. The reaction mixture was poured into water, made acidic with hydrochloric acid, and extracted with ethyl acetate. The organic layer was washed with water, dried over anhydrous sodium sulfate, and evaporated. The residue was purified by silica gel column chromatography (chloroform:methanol=15:1), to thereby obtain 20 mg (yield: 23.8%) of the title compound as a pale yellow oil.
