Reaction Steps
To a solution of 3-(2-bromoethyl)-1-(4-fluorophenyl)-2-methyl-5-[4-(methylsulphonyl)phenyl]-1H-pyrrole (0.80 mmol) in dry DMF (10 mL) was added sodium iodide (0.80 mmol) and the resulting mixture was stirred at r.t. for 30 min. Potassium phthalimide (0.90 mmol) was then added, and the reaction mixture was heated at 70° C. for 14 h. After cooling the mixture was poured onto crushed ice and extracted with CH2Cl2. The organic phase was thoroughly washed with water to remove the DMF excess, dried and concentrated under reduced pressure. The residue, purified by flash-chromatography (EtOAc/hexane 1:1 v/v), gave the expected compound as an oil which crystallizes on standing. Yellowish needles from EtOAc Mp 198-201° C. (yield 70%) 1H-NMR (CDCl3) δ ppm: 2.04 (s, 3H), 2.86 (t, 2H, J=7.5), 2.98 (s, 3H), 3.88 (t, 2H, J=7.6), 6.42 (s, 1H), 7.07 (m, 6H), 7.61-7.74 (m, 4H), 7.81-7.85 (m, 2H).
