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, 121 mg, 0.298 mmol) and THF (2 mL). To the resulting solution was added 4-(2-Pyrrolidin-1-yl-ethoxy)-phenylamine1 (67.7 mg, 0.329 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature. Hexanes were added to the reaction mixture, and the resulting suspension was filtered. The filtrate then was concentrated in vacuo. The residue was redissolved into EtOAc then diluted with Hexanes causing a precipitate to form. This precipitate was filtered and washed with ˜1 mL of i-prOH yielding 62% (0.109 g, 0.185 mmol) of the title compound.
