A small screw cap test tube was charged with 5-Acetyl-thiophene-2-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 54, 100 mg, 0.231 mmol) and THF (2 mL). To the resulting solution was added N-(4-aminophenyl)morpholine (45.34 mg, 0.254 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature. Hexanes (5 mL) were added to the reaction mixture. The crude mixture was concentrated in vacuo and then dissolved into hot EtOAc. Hexanes (˜5 mL) were added causing a precipitate to crash out. The precipitate was filtered and washed with ˜1 mL of i-prOH yielding 69% (95 mg, 0.160 mmol) of the title compound.
