Triethylamine → HCID 21922598, compound

Participants

Reaction Steps

1.99 g (6.09 mmol) of p-toluenesulfonic anhydride and 0.85 ml (6.09 mmol) of triethylamine were added to a solution of 1.64 g (5.53 mmol) of 3-(4-fluorophenyl)-1-(3-hydroxypropyl)-2-(pyridin-4-yl)-1H-pyrrole [prepared as described in step 22(ii) above] in 16 ml of dichloromethane. The resulting mixture was stirred at room temperature for 2 hours, after which the solvent was distilled off by evaporation under reduced pressure. The resulting residue was purified by chromatography on a silica gel column using a 1:1 by volume mixture of hexane and ethyl acetate as the eluant to afford 1.33 g (yield 53%) of the title compound as a yellow powder.
