実験手順

((S)-7-Amino-6-oxo-6,7-dihydro-dibenzo[b,d]azepin-5-yl)-acetic acid methyl ester (25 mg, 0.85 mmol) were dissolved in THF and subsequently treated with 2-methyl-N-(2,2,3,3,3-pentafluoro-propyl)-malonamic acid (25 mg, 0.1 mmol), 1-hydroxybenzotriazole (11.6 mg, 0.85 mmol), N-ethyldiisopropylamine (0.03 ml, 0.17 mmol) and EDC (16.5 mg, 0.85 mmol). After stirring for 2.5 h at ambient temperature, the reaction mixture is quenched with water and extracted with ethyl acetate. The aqueous phase is extracted twice with ethyl acetate and the combined organic layers are extracted with water (2×5 ml) and saturated aqueous sodium chloride (5 ml), combined, dried over anhydrous sodium sulfate and evaporated to dryness. Chromatography (silica, eluent cyclohexane/ethyl acetate 65/35) afforded the product as colorless solid (70%). MS: m/e=528 (M+H+).
