Reaction Steps

A small screw cap test tube was charged with 2-Ethyl-5-methyl-2H-pyrazole-3-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 69, 100 mg, 0.2401 mmol) and THF (3.0 mL). To the resulting solution was added 4-(4-Amino-phenyl)-butyric acid (43 mg, 0.24 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature and diluted with EtOAc (˜5 mL) and Hexane (˜50 mL). The precipitate that formed was collected by filtration and washed with 0° C. iPrOH (˜5 mL) to afford the title compound in 29% yield (0.040 g, 0.0692 mmol).
