実験手順

To a solution of (2E)-5-(((9H-flouren-9-yl)methoxy)- carbonylamino)-5-methylhex-2-enoic acid (280 mg, 0.77 mmol) in dichloromethane (5 ml) were added 1-hydroxy-7-azabenzotriazole (126 mg, 0.92 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (207 mg, 1.08 mmol) and the mixture was stirred for 30 min. Then 2R)-N-((1R)-1-dimethylcarbamoyl-2-phenylethyl)-N-methyl-2-methylamino-3-(2-naphthyl)propionamide (386 mg, 0.92 mmol) in dichloromethane (5 ml) and diisopropylethylamine (0.17 ml, 1.00 mmol) were added and the mixture was stirred overnight at room temperature. The mixture was washed with water (20 ml), saturated aqueous sodium bicarbonate (20 ml), water (2×20 ml), brine (20 ml), dried over magnesium sulfate and concentrated in vacuo. The crude product was chromatographed on silica (400 g) with ethyl acetate/heptan 1:1 to give 401 mg of ((3E)-4-(N-((1R)-1-(N-((1R)-1-dimethylcarbamoyl-2-phenylethyl)-N-methylcarbamoyl)-2-(2-naphthyl)ethyl)-N-methylcarbamoyl)-1,1-dimethylbut-3-enyl)carbamic acid 9H-flouren-9-ylmethyl ester. The obtained product was dissolved in 20% piperidine in dimethylformamide (10 ml) and stirred for 30 min. The mixture was chromatographed on silica (20 g) with dichloromethane/methanol/ammonia 89:10:1 to give 228 mg of (2E)-5-amino-5-methylhex-2-enoic acid N-((1R)-1-(N-((1R)-1-(dimethylcarbamoyl)-2-phenylethyl)-N-methylcarbamoyl)-2-(2-naphthyl)ethyl)-N-methylamide as an oil. The product was redissolved in water (30 ml) and acetic acid (2 ml) was added and the mixture was lyophilized to give 645 mg of the acetate salt of the title compound as an amorphous powder.
