실험 절차

Add 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (29 g, 151 mmol) to a 10° C. slurry of (4R)-5,6-dihydro-4H-imidazo[1,2-a][1]benzazepin-4-amine (30 g, 151 mmol), 1-hydroxybenzotriazole (20 g, 151 mmol), triethylamine (41.97 mL, 301 mmol), and 1-[(4-chlorobenzoyl)amino]cyclopropanecarboxylic acid (40 g, 166 mmol) in THF (300 mL). Remove the ice bath, warm the mixture to ambient temperature, and stir it for 4 hours. Pour the mixture into water (1.0 L) and extract with ethyl acetate (1.0 L). Wash the organic phase with saturated sodium bicarbonate (500 mL), dry over magnesium sulfate, filter, and concentrate under reduced pressure. Slurry the residue in ethyl acetate (300 mL) and heat to 71° C. Cool to ambient temperature, filter the precipitate, and wash with ethyl acetate (100 mL) to give the title compound (38.8 g, 61%): MS (m/z): 421 (M+1).
