実験手順

HATU (194 mg, 0.510 mmol), N,N-diisopropylethylamine (143 μL) and methyl-pent-4-enyl-amine (80 mg) were added to a solution of 4-{2-[2-(3-but-3-enyloxy-5-trifluoromethyl-phenyl)-4-oxo-1,3,8-triaza-spiro[4.5]dec-1-ene-8-sulfonyl]-ethyl}-3-methyl-benzoic acid (200 mg, 0.337 mmol) in DMF (3 ml), and the mixture was stirred at room temperature overnight. A saturated aqueous ammonium chloride solution was added to the reaction solution, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated brine, and then dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography to give 4-{2-[2-(3-but-3-enyloxy-5-trifluoromethyl-phenyl)-4-oxo-1,3,8-triaza-spiro[4.5]dec-1-ene-8-sulfonyl]-ethyl}-3,N-dimethyl-N-pent-4-enyl-benzamide (192 mg, 84%).
