실험 절차

{2-[3-bromo-(5-trifluoromethyl-pyridin-2-yloxy)-phenyl]-ethyl}-carbamic acid tert-butyl ester (1.3 g, 2.818 mmol) was dissolved in dichloromethane (10 ml) and stirred at 0° C. for 5 min TFA (1.08 ml, 14.091 mmol, 5 eq) was added and stirring was continued overnight. Reaction mixture was diluted with 10 ml NaHCO3 (sat.) and extraction with DCM (3×20 ml) followed. Organic layers were combined and evaporated in vacuo to give 2-[3-bromo-(5-trifluoromethyl-pyridin-2-yloxy)-phenyl]-ethylamine (1.01 g, 2.796 mmol, yield=99%, purity=100%). [M+H]+=361.17
