To a mixture of 5,6-dihydro-4H-imidazo[1,2-a][1]benzazepin-4-amine (400 mg, 2.01 mmol), 1-(4-cyclopropoxybenzamido)cyclopropanecarboxylic acid (577 mg, 2.21 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (462 mg, 2.41 mmol) and 1-hydroxybenzotriazole hydrate (369 mg, 2.41 mmol) in dichloromethane (8 mL), add triethylamine (1.26 mL, 9.03 mmol) and stir the mixture at ambient temperature for approximately 16 hours. Purify the crude mixture by flash chromatography (0% to 5% MeOH/dichloromethane) to give the title compound (791 mg, 89%) as a tan foam: MS (m/z): 443 (M+1).
