Participants

Reaction Steps

A solution of N-(3-amino-phenyl)-N-benzyl-benzene sulfonamide (25 mg, 0.07 mmol), 3-methyl-3H-imidazole-4-carboxylic acid (14 mg, 0.11 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (16 mg, 0.08 mmol), mercaptobenzothiazole (2 mg, 0.007 mmol) and triethylamine (25 μl, 0.18 mmol) in dry acetonitrile (1 ml) were stirred at room temperature for 15 hrs. The reaction mixture was quenched with water (10 ml), extracted with dichloromethane (3×7 ml) and the combined organics concentrated in vacuo. The crude residue was purified by preparative TLC (SiO2) eluting with ethyl acetate/dichloromethane (1:1) to afford the title compound as an off white solid (2.8 mg, 8%). HPLC retention time 5.6 min. Mass spectrum (ES+) m/z 447 (M+H).
