実験手順

To a solution of allyl 2-[5-(2,4-dimethylbenzoyl)-1-methylpyrrol-2-yl)-2-(2-fluoro-4-nitrophenyl)acetate (3.6 g, 7.99 mmol) [prepared as described in Example 6, Step (d)] in anhydrous THF (40 ml) was added morpholine (6.99 ml, 79.90 mmol) and tetrakis(triphenylphosphine) palladium (9 mg, 0.008 mmol)). After 1.5 h, the solvent was evaporated and the residue was partitioned between ether and 1N NaHSO4. The organic layer was separated, dried over magnesium sulfate, and concentrated to dryness. Purification by column chromatography (ethyl acetate/hexane) gave 4-[5-(2,4-dimethylbenzoyl)-1-methyl-pyrrol-2-yl-methyl)nitrobenzene (2.73 g, 93%) as a pale yellow oil. ##STR37##
