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 3-(4-Amino-phenyl)-propionic acid (45.2 mg, 0.274 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature and concentrated in vacuo. The resulting residue was redissolved into EtOAc. Hexanes were added to the EtOAc solution causing a precipitate to form. The solid precipitate that formed was washed with ˜1 mL of i-prOH yielding 15.4% (0.021 g, 0.038 mmol) of the title compound.
