実験手順

A small screw cap test tube was charged with 2-Ethyl-5-methyl-2H-pyrazole-3-carboxylic acid [4-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (prepared below, 100 mg, 0.240 mmol) and THF (1 mL). To the resulting solution was added N-(4-aminophenyl)morpholine (47.08 mg, 0.264 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 crude residue was purified via flash silica gel chromatography (5% MeOH/95% CHCl3) yielding 67% (94 mg, 0.163 mmol) of the title compound.
