実験手順

To a dimethylformamide (2 mL) solution of the compound (300 mg) produced in Example 29 and 4-formylbenzoic acid (116 mg), 1-ethyl-3-[3-(dimethylamino)propyl]carbodiimide (hereafter abbreviated to EDC) (274 mg) and 1-hydroxybenzimidazole (104 mg) were added in this order. The reaction solution was stirred at room temperature for 17 hour. To the reaction solution, water (10 mL) was added. The aqueous layer was extracted twice with dichloromethane (20 mL). The combined organic layer was washed with saturated sodium chloride solution (20 mL) and then dried over anhydrous magnesium sulfate. After removing the anhydrous magnesium sulfate by filtration, the filtrate was concentrated. The residue was purified by silica gel chromatography (ethyl acetate:methanol: 28% aqueous ammonia=1:0:0→100:10:1) to obtain the title compound (510 mg).
