Reaction Steps

A solution of bromine (0.8 ml, 2.5g) in chloroform (20 ml) was added over 20 min to a stirred solution of 1-[3-[2-(acetyloxy)ethyl]-4-hydroxyphenyl]ethanone (3.26 g ) in chloroform (50 ml) containing a few drops of 45% hydrogen bromide in acetic acid. The red solution was diluted with ER (200 ml) washed with water (100 ml), 8% sodium bicarbonate (100 ml), brine (100 ml), dried and evaporated to give the title compound as an oil which solidified on standing to give a pale pink solid (4.1 g) m.p. 89°-92°. Two recrystallisations from chloroform gave a sample with m.p. 98°-99°.
