Procedure

A solution of 13-cyclohexyl-6-[[4-(4-morpholinyl)-1-piperidinyl]carbonyl]-7H-indolo[2,1-a][2]benzazepine-10-carboxylic acid (40 mg, 0.07 mmol), N,N-diisopropylethylamine (60 μL, 0.34 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (19 mg, 0.1 mmol), 1-hydroxybenzotriazole (14 mg, 0.1 mmol), and (R)-(−)-tetrahydrofurfurylamine (10 mg, 0.1 mmol) in CH2Cl2 (1.5 mL) was stirred at r.t. overnight, diluted with CH2Cl2 (5 mL), and chromatographed on silica gel (gradient elution: 0%→10% MeOH in CH2Cl2) to afford a yellow oil. Et2O (5 mL) was added to dissolve the oil, and concentration afforded the title compound as an off-white solid (32 mg, 72% yield).
