Reaction Steps

To an ice cooled solution of 1-naphthylamine-5-sulfonic acid (2 g, 8.9 mmol) in dichloromethane (5 mL), was added triethylamine (1.87 mL, 13.4 mmol). Benzoyl chloride (1.14 ml, 9.85 mmol) was added and the resultant solution was stirred at room temperature overnight. The reaction mixture was quenched by pouring into ice water, and the product was extracted into ethyl acetate. The organic extracts were washed with brine, dried over MgSO4, filtered and concentrated to provide crude intermediate 43 as a white solid that was used without further purification.
