Trifluoroacetic acid → Methyl-{2-[4-(3-trifluoromethyl-phenoxy)-phenyl]ethyl}-amine

Participants

Reaction Steps

Methyl-{2-[4-(3-trifluoromethyl-phenoxy)-phenyl]-ethyl}-carbamic acid tert-butyl ester (300 mg, 0.759 mmol, 1 eq) was dissolved in dry DCM (3 ml) under argon atmosphere and TFA (290.6 μl, 5 eq) was added. Reaction mixture was stirred for overnight. In the reaction mixture was added more DCM (15 ml) and was extracted with saturated NaHCO3 (3×15 ml) and brine. Organic layer was dried over anhydrous Na2SO4, filtered and evaporated to give a product methyl-{2-[4-(3-trifluoromethyl-phenoxy)-phenyl]ethyl}-amine (211.5 mg, yield=82.1%, purity=87%).
