Procedure
Add 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC; 98 mg, 0.51 mmol, 1.5 equiv) and 4-(dimethylamino)pyridine (DMAP; 70 mg, 0.57 mmol, 1.7 equiv) to a solution of 4-(3-cyclopentylindole-1-sulfonyl)benzoic acid (126 mg, 0.341 mmol, 1 equiv) and (R)-(−)-tetrahydrofurfurylamine (Aldrich; 140 μL, 140 mg, 1.4 mmol, 4.0 equiv) in anhydr CH2Cl2 (1 mL). After stirring 16 h, transfer the reaction solution to a column of silica gel (80 mm×20 mm dia.) and elute (10-45% EtOAc/hex) to give 24 mg (16%) of 4-(3-cyclopentylindole-1-sulfonyl)-N—[(R)-1-(tetrahydrofuran-2-yl)methyl]benzamide as a white foam. MS (m/e): 452.96 (M+1); 451.14 (M−1).
