Add 10 ml dry DMF to a flask under N2 containing 4-(3-Phenyl-indole-1-sulfonyl)-benzoic acid (500 mg, 1.33 mmol, 1.0 eq), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (279 mg, 1.46 mmol, 1.1 eq), Dimethyl-pyridin-4-yl-amine (16 mg, 0.132 mmol, 0.1 eq), and C-Pyrazin-2-yl-methylamine (217 mg, 1.99 mmol, 1.5 eq). Stir for 18 hours at room temperature. Remove solvent on rotovap and purify by silica gel chromatography to give 4-(3-Phenyl-indole-1-sulfonyl)-N-pyrazin-2-ylmethyl-benzamide (127 mg, 20% yield). Mass Spectrum (m/e): 468.95 (MH+).
