Reaction Steps

A small screw cap test tube was charged with 5-Ethyl-1-methyl-1H-pyrazole-3-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 345, 60 mg, 0.1441 mmol) and THF (2.0 mL). To the resulting solution was added 3-(4-Amino-phenyl)-propionic acid (24.2 mg, 0.146 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 (˜40 mL). The solid that precipitated was collected by filtration and washed with 0° C. iPrOH (˜10 mL) affording the title compound in 41% yield (0.033 g, 0.059 mmol).
