Hydrochloric Acid → 3-[2-(3',4'-dimethylbiphenyl-3-yl)-9-hydroxy-3H-naphtho[1,2-d]imidazole-7-sulfonylamino]-benzoic Acid

Participants

Reaction Steps

To an agitated suspension of 3-aminobenzoic acid (0.028 g, 0.2 mmol) in THF (1 mL) was added 2-(3′,4′-dimethylbiphenyl-3-yl)-9-hydroxyl-3H-naphtho[1,2-d]imidazole-7-sulfonyl chloride (0.083 g, 0.18 mmol) and sodium hydroxy (0.018 g, 0.4 mmol) in water (0.5 mL). After agitated for 30 minutes, the reaction mixture was added 6N hydrochloride (2 ml) and concentrated under reduced pressure. The residue was subjected to HPLC (ODS-A, gradient 10-90% CH3CN/water 0.1% TFA) to provide the title compound (0.005 g, 4%) MS(ES) m/z 564 [M+H].
