Participants

Reaction Steps

Add a 2 ml CH2Cl2 solution of Tetrahydro-pyran-4-ylamine (62 mg, 0.0610 mmol, 1.1 eq) and triethylamine (365 mg, 3.6 mmol, 6.5 eq) to a 2 ml CH2Cl2 solution of 4-[3-(3,3-Difluoro-cyclopentyl)-indole-1-sulfonyl]-benzoic acid. Add benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (245 mg, 0.555 mmol, 1.0 eq) and stir reaction at room temperature for 18 hours. Remove volatiles on rotovap and purify by silica gel chromatography, followed by SCX ionic chromatography to give 4-[3-(3,3-Difluoro-cyclopentyl)-indole-1-sulfonyl]-N-(tetrahydro-pyran-4-yl)-benzamide (240 mg, 89% yield). Mass Spectrum (m/e): 489.71 (MH+).
