Reaction Steps

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-phenyl)-acetic acid (41.4 mg, 0.274 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature. EtOAc (3 mL) was added to the mixture and was washed with 5% HCl(aq) (2 mL) and H2O (2×2 mL). The organic layers were combined dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The solid was then recrystallized from EtOAc/Hexanes affording 51% (0.068 g, 0.127 mmol) of the title compound.
