Yield:106877-47-8 260 mg
Reaction Conditions:
with BBr3 in 1,2-dichloro-ethane at 0 - 25; for 14 h;
Steps:
501.1 Step-1. 5-amino-2-(trifhioromethyl)phenol
BBi'3 (28.3 mL, 28.24 mmol) was added to a solution of 3-methoxy-4-(trifluoromethyl) aniline (270.0 mg, 1.41 mmol) in DCE (5.00 mL) at 0 °C. The resulting mixture was stirred at 25 °C for 14 h. The resulting mixture was concentrated under vacuum. The residue was purified by silica gel column chromatography eluting with DCM/MeOH (15/1 v/v) to obtain the title compound (260.0 mg) as a solid. LCMS (ESI): 178.00 [M+H]+.
