Versuchsvorschrift
A solution of 1-(3-Bromo-5-chloromethyl-2-hydroxy-phenyl)-ethanone 212 (7.6 mmol) in 6 mL DMSO is added dropwise to a suspension of 8.2 mmol of NaCN in 4 mL DMSO. The mixture is stirred for 12-18 h and diluted with 80 mL water to yield a solid. The solid is isolated and recrystallized from ethanol to yield (3-acetyl-5-bromo-4-hydroxy-phenyl)-acetonitrile 213 in a 58% yield.
