Triethylamine → 4-(3-Cyclohexyl-indole-1-sulfonyl)-N-(4-fluoro-benzyl)-benzamide

Participants

Reaction Steps

Add 4-Fluoro-benzylamine (72 mg, 0.574 mmol, 1.1 eq) followed by triethylamine (343 mg, 0.472 ml, 3.39 mmol, 6.5 eq) to a CH2CL2 solution (8 ml) of 4-(3-Cyclohexyl-indole-1-sulfonyl)-benzoic acid (200 mg, 0.521 mmol, 1 eq). Add benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (231 mg, 0.521 mmol, 1 eq) and stir at room temperature for 16 hours. Remove solvent on rotovap and purify crude by silica gel chromatography to give 4-(3-Cyclohexyl-indole-1-sulfonyl)-N-(4-fluoro-benzyl)-benzamide (232 mg, 99% yield). Mass Spectrum (m/e): 490.92 (MH+).
