실험 절차

To a solution of compound 54 (100 mg, 0.483 mmol), methylamine hydrochloride (52.2 mg, 0.773 mmol), HOBt (130 mg, 0.966 mmol) and DIEA (0.34 mL, 1.95 mmol) in N-methylpyrrolidinone was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (148 mg, 0.773 mmol). The reaction was stirred at room temperature for 2 hrs and diluted with 10 mL of ethyl acetate. The mixture was washed with water and a yellow solid precipitated. The precipitate was collected by filtration to give compound 55 (67 mg).
