Reaction Steps
To 5-acetyl-2-hydroxyphenylacetonitrile (3.5 g., 0.02 mole) in 100 ml. of tetrahydrofuran is added trimethylphenylammonium tribromide (7.6 g., 0.02 mole) portionwise over a 15 min. period with stirring. After stirring for an additional 18 hrs. at 25° C., the reaction mixture is concentrated to dryness under reduced pressure. Trituration of residual material with water affords 5.0 g. of brominated product, m.p. 187°-191° C. (dec.). Crystallization of this material from isopropanol affords 5-bromoacetyl-2-hydroxyphenylacetonitrile, m.p. 196°-198° C. (dec.).
