Participants

Reaction Steps

A solution in DMF (2.0 ml) of [2-(bromomethyl)phenyl]boronic acid (399 mg) was added in one portion to a stirred slurry of sodium methanesulphinate (200 mg) in DMF (2.0 ml). The mixture was stirred for 2.5 h i nd then poured into 1M hydrochloric acid (100 ml) and extracted with EA (3×50 ml). the combined extracts were dried and evaporated. On standing a solid material precipitated, which was washed with ER to give white crystals of the title compound (115 mg), m.p. 133°-137°. T.l.c. (A) ER:hexane (3:2) Rf 0.51.
