4-broMo-2-chloro-5-(trifluoroMethoxy)aniline synthesis

Yield:115844-00-3 64%

Reaction Conditions:

with N-chloro-succinimide in quinoclamine;ethyl acetate;

Steps:

62.a (a)

(a) 4-Bromo-2-chloro-5-trifluoromethoxy-phenylamine To a mixture of 4-bromo-3-trifluoromethoxy-phenylamine (2.0 g, 7.8 mmol) in ACN (60 mL) was slowly added a solution of N-chlorosuccinimide (1.0 g, 7.8 mmol) in ACN (40 mL). The reaction mixture was heated at 60° C. overnight and extracted with ethyl actetate/water. The organic layer was dried over sodium sulfate and purified by flash chromatography (40 g column, 100% hexanes to 10% EtOAc:hexanes) to produce the desired product as an orange-ish colored oil (1.4 g, 64% yield).
