Reaction Steps
A solution of 2-(2-chloro-4-methoxy-phenyl)-2-methyl-propionitrile (17.5 g, 0.0835 mol) in TFA (100 mL) was cooled to 0° C. N-bromosuccinimide (14.9 g, 0.0835 mol) was added in small portions keeping the temperature below 5° C. The orange solution was stirred for 2 h/25° C. and evaporated to dryness. Water (200 mL) was added and the mixture was stirred vigorously for 1 h. The crude product was filtered off and recrystallized from boiling MeOH. The pure product was isolated as white needles. Yield: 13 g (54%). GCMS: >99%
