Reaction Steps
To a stirred solution of 2-aminoethanol (5 ml, 150 mmol) in THF (20 ml), 1-fluoro-2-nitro-4-(trifluoromethyl)benzene (6.9 ml, 50 mmol) was added slowly at 0° C. After the completion of the addition, the reaction mixture was stirred at RT for 24 hrs. THF was evaporated using a rotary evaporator and the residue was extracted using water and ethyl acetate. Ethyl acetate was washed with more water, dried and evaporated to give crystalline 2-aminoethanol derivative (10.0 g, 80%).
