Participants

Reaction Steps

3-(4-Methoxyphenylsulfonyl)-2-phenylbenzofuran (1.9 g.) was combined with 12 g. of freshly distilled pyridine hydrochloride and heated at 210° for 3.5 hours. The hot mixture was poured onto an ice-dilute hydrochloric acid mixture and the precipitate formed was collected by filtration and dissolved in chloroform. The chloroform solution was extracted three times with water and then with a saturated sodium chloride solution, refluxed with decolorizing charcoal, filtered and dried (MgSO4). Evaporation of the solvent gave 3-(4-hydroxyphenylsulfonyl)-2-phenylbenzofuran, m.p. 166°-168°.
