실험 절차

To a solution of methyl 2-[5-(2,4-dimethylbenzoyl)-1-methylpyrrol-2-yl)-2-(2-fluoro-4-nitrophenyl)acetate (3.51 g, 8.27 mmol) [prepared as described in Example 6, Step(c)] in 75 ml allyl alcohol was added titanium tetraisopropoxide (0.244 ml, 0.827 mmol), and the reaction mixture was heated to reflux. After 36 h, the reaction mixture was cooled to room temperature, and partitioned between ether and water. The organic layer was separated, dried over magnesium sulfate, and concentrated to dryness to give allyl 2-[5-(2,4-dimethylbenzoyl)-1-methylpyrrol-2-yl)-2-(2-fluoro-4-nitrophenyl)-acetate (3.60 g, 97%) as a pale yellow oil. ##STR35##
