Reaction Steps

To a solution of 5-(3-Trifluoromethyl-phenylmethanesulfonyl)-1,3-dihydro-indol-2-one (100 mg, 0.28 mmol) and 5-formyl-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (2-diethylamino-ethyl)-amide (75 mg, 0.28 mmol) in ethanol (4 mL) was added piperidine (0.1 mL). The reaction mixture was stirred at 25° C. for three days. The solvent was evaporated and the residue was purified on a silica gel column eluting with MeOH—CH2Cl2 1:9 to provide 105 mg (62%) of 2,4-dimethyl-5-[2-oxo-5-(3-trifluoromethyl-phenylmethanesulfonyl)-1,2-dihydro-indol-(3Z)-ylidenemethyl]-1H-pyrrole-3-carboxylic acid (2-diethylamino-ethyl)-amide as a pale orange solid.
