実験手順

Crude 4-amino-3-hydroxy-azepane-1-carboxylic acid benzyl ester (150 mg, 0.57 mmol) prepared as in Reference 2, 2-[(morpholine-4-carbonyl)-amino]-3-phenylmethanesulfonyl-propionic acid (400 mg, 1.12 mmol), EDC (400 mg, 2.1 mmol), and HOBt (400 mg, 2.5 mmol) were combined. Dichloromethane (10 mL) was added followed by 4-methylmorpholine (0.5 mL). The mixture was stirred at ambient temperature for 2 hours. After dilution with ethyl acetate (100 mL) the solution was washed with 1N HCl, saturated aqueous NaHCO3 and brine, dried with MgSO4 and evaporated under vacuum. The residue was purified by flash chromatography (ethyl acetate/methanol 9: 1) to yield 3-hydroxy-4-{2-[(morpholine-4-carbonyl)-amino]-3-phenylmethanesulfonyl-propionyl-amino}-azepane-1-carboxylic acid benzyl ester (320 mg).
