Procedure

A small screw cap test tube was charged with 2,5-Dimethyl-2H-pyrazole-3-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 60, 100 mg, 0.249 mmol) and THF (2 mL). To the resulting solution was added 4-Amino-benzoic acid (37.5 mg, 0.274 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature. The yellow solid was dissolved into a solution of 98% EtOAc/2% i-prOH (3 mL) and washed with water (3×2 mL). The organic layers were combined and dried over anhydrous Na2SO4 affording 47.8% (0.062 g, 0.119 mmol) of the title compound.
