Reaction Steps

A reactor vessel is charged with 3-aminopyridine (2.0 g, 21 mmol), 2,2,2-trifluoroethanol (15 g, 150 mmol), and trifluoroacetic acid (3.63 g, 31.8 mmol). The solution is cooled to 15° C. and then t-Butylnitrite (2.51 g of a 96% solution, 23.4 mmol) is added drop-wise to the vessel so that the temperature rises to the range 25° C.-30° C. Potassium carbonate (4.4 g) is added to the vessel and the reaction mass is stirred overnight followed by dilution with water and extraction with ethyl acetate. The solvent is evaporated to obtain 3-(2,2,2-trifluoroethoxy)pyridine as a crude oil (3.94 g, crude yield 59.5%) with an actual yield of 56.8%.
