Procedure
1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.68 g) was added to a dichloromethane solution (15 mL) of the compound (0.90 g) obtained in Step 3 of Example 25 and 4-methylsulfonylphenylacetic acid (0.76 g) and the mixture was stirred at room temperature for one hour. The reaction mixture was poured into cold water (80 mL) and then separated, and the aqueous layer was extracted with dichloromethane. The organic layer was combined and washed with water and brine successively, and then dried over anhydrous sodium sulfate. After the solvent was removed under reduce pressure, the residue was purified by silica gel column chromatography (eluent; dichloromethane:methanol=8:1) to obtain the titled compound (1.36 g) as crystals.
