実験手順

2-(tert Butoxycarbonylmethylamino)-3-(2-naphthyl)propionic acid (1.20 g; 3.55 mmol) was dissolved in methylene chloride (10 ml). 1-Hydroxy-7-azabenzotriazol (0.48 g ;3.55 mmol) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.75 g; 3.90 mmol) were added. The reaction mixture was stirred for 15 min at room temperature. 2R)-N-Methyl-2-methylamino-3-(thiophen-2-yl)propionamide (0.70 g; 3.55 mmol) was dissolved in methylene chloride (10 ml) and added. Diisopropylamine (0.61 ml; 3.55 mmol) was added. The reaction mixture was stirred at room temperature for 2 days. Methylene chloride (10 ml) and water (10 ml) were added to the reaction mixture. The phases were separated and the organic phase was washed with aqueous sodium hydrogensulfate (10%; 20 ml), saturated aqueous sodium hydrogencarbonate (20 ml). The organic phase was dried over magnesium sulfate and the solvent was removed in vacuo. The crude product was chromatographed on silica (2×20 cm) using ethylacetate/heptane (1:1) as eluent to afford 1.38 g of N-methyl-N-((1R)-1-(N-methyl-N-((1R)-1-(methylcarbamoyl)-2-(thiophen-2-yl)ethyl)carbamoyl)-2-(2-naphthyl)ethyl) carbamic acid tert butylester.
