실험 절차

A mixture of 3-(1,3-dioxolan-2-yl)-1-(4-fluorophenyl)propan-1-one (Example 8, Step 2) (1.6 g, 7.14 mmol), sulfanilamide (1.35 g, 7.86 mmol), p-toluenesulfonic acid (120 mg) and molecular sieves (4 Å, 3 g) in toluene (250 ml) was heated to reflux for 98 hours. The reaction was cooled, filtered and concentrated. The crude brownish solid (3.2 g) was purified by chromatography (silica gel, hexane/ethyl acetate, 6/4) to give 4-[2-(4-fluorophenyl)-1H-pyrrol-1-yl]benzenesulfonamide (920 mg, 40%) as a white solid: mp (DSC) 206° C. Anal Calc'd. for C16H13N2SFO2 ·0.2 H2O: C, 60.06; H, 4.22; N, 8.76; S, 10.02. Found: C, 60.13; H, 4.21; N, 8.61; S, 10.15.
