反応手順

NH4OH (4 mL) was added to a premixed (15 min) solution of N-(t-butoxycarbonyl)-L-homophenylalanine (4.00 g, 14.3 mmol), EDC (3.24 g, 17.2 mmol), and HOBT (2.32 g, 17.2 mmol) in DMF (20 mL) at room temperature. After 16 h the reaction mixture was diluted with CH2Cl2 and filtered, washed sequentially with 10% aqueous HCI, satd. NaHCO3, H2O (×3), brine, dried over Na2SO4, and concentrated giving N-(t-butoxycarbonyl)-L-homophenylalaninamide (3.10 g, 78%) as a white solid.
