Procedure

A solution of 1-(5-chloro-2-methoxy-benzenesulfonyl)-4-methyl-2,3-dihydro-1H-indole-6-carboxylic acid (150 mg, 0.393 mmol), ethyl 4-aminobenzoate (130 mg, 0.786 mmol), 4-methylmorpholine (199 mg, 1.96 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluoro-phosphate (224 mg, 0.589 mmol) in N,N-dimethylformamide (1.5 mL) was stirred at room temperature for 15 min, then 4-(dimethylamino)pyridine (49 mg, 0.39 mmol) was added, and the solution was stirred at 60° C. for 18 h. After cooling, the reaction mixture was partitioned between water, heptane, and ethyl acetate. The organic layer was washed with brine, dried (MgSO4), and evaporated. Chromatography (SiO2, heptane-ethyl acetate gradient) produced 4-{[1-(5-chloro-2-methoxy-benzenesulfonyl)-4-methyl-2,3-dihydro-1H-indole-6-carbonyl]-amino}-benzoic acid ethyl ester (190 mg, 91%). White solid, MS (ISP): m/e 529.2 (M+H).
