反応手順
A suspension of 1,3-dihydro-5-fluoro-4-iodo-2H-indol-2-one (0.5 g, 1.8 mmol) (Example 2A) and 5-formyl-4-methyl-1H-pyrrole-3-carboxylic acid ethyl ester (0.39 g, 2.17 mmol) (Example 116A above) in 1% piperidine in 2-propanol (6 mL) was heated at 80° C. for 3 h. The precipitate was collected and washed with water to give (Z)-5-(5-Fluoro-4-iodo-2-oxo-1,2-dihydro-indol-3-ylidenemethyl)-4-methyl-1H-pyrrole-3-carboxylic acid ethyl ester. (Yield 0.67 g, 85%).
