Reaction Steps

To a solution of 1-(bromomethyl)-4-(trifluoromethyl)benzene (0.87 ml, 5.6 mmoles) in DMF (10 mL), cesium carbonate (3.35 gm, 10.2 mmoles) was added followed by addition of methyl 2-((5-(1-(hydroxyimino)ethyl)pyridin-2-yl)oxy)acetate (1.15 gm, 5.1 mmoles) at 25° C. under nitrogen atmosphere and the reaction mixture was stirred at the same temperature for 12 h. The reaction mixture was poured into ice cold water and extracted with ethyl acetate. The combined ethyl acetate extract was washed with water & brine, dried over sodium sulphate and evapourated under reduced pressure to yield 2.0 gm (94%) of product as thick liquid.
