실험 절차

To a solution of 2-{6,6-dimethyl-1-[2-(trimethylsilyl)ethoxymethyl]-4,5,6,7-tetrahydro-1H-indazol-3-yl}-1-[2-(trimethylsilyl)ethoxymethyl]-1H-indole-6-carboxylic acid obtained in Example 1, Step 4 (500 mg, 0.88 mmol) in N,N-dimethylformamide (5 ml) were added 1-hydroxybenzotriazole monohydrate (161 mg, 1.1 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (202 mg, 1.1 mmol) and 2-amino-1-propanol (84 mg, 1.1 mmol) at room temperature, and the mixture was stirred at room temperature for 7 hr. To the reaction mixture were added water and ethyl acetate, and the organic layer was separated. Then, the organic layer was washed successively with water and saturated brine, and dried over sodium sulfate. Sodium sulfate was removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography to give the title compound (511 mg, yield 93%).
