실험 절차

The compound obtained in Example 8-6 (165.3 mg) was dissolved in DMF (3 ml). After the addition of WSCI hydrochloride (78.5 mg), HOBt (40.1 mg), and the compound obtained in Example 12-3 (90.4 mg), the mixture was stirred for 23 hours at room temperature. After the reaction, the solvent was removed by distillation. The residue was dissolved in chloroform and washed with 1 mol/l aqueous solution of hydrochloric acid, 1 mol/l aqueous solution of sodium hydroxide, and saturated brine. The organic layer was dried over anhydrous sodium sulfate and the solvent was removed by distillation. The residue was purified by silica gel column chromatography (10 g, chloroform/methanol=20/1) to obtain the title compound (167.6 mg) as white foam.
