Reaction Steps
Sodium methoxide (51.84 g) was added to dry toluene (815 mL) in a 1 L reactor under a nitrogen atmosphere. The reaction mixture was heated to 75° C., and then a mixture of 2-fluorobenzeneacetonitrile (100 g) in dimethyl carbonate (131.64 g) was added at 70-74° C. over a period of 45 minutes. The reaction mixture was further maintained at this temperature (70-75° C.) for an additional 4.5 hours. The reaction mixture was then cooled to 25-30° C. and added to a mixture of HCl (110 g, 35.2 wt %) diluted with water (300 mL) at 10-15° C. using an addition funnel. The resulting layers were separated, and the aqueous layer was extracted with ethyl acetate (2×200 mL). The combined organic layers were washed with water (2×200 mL), dried over sodium sulfate, and concentrated under reduced pressure to provide the title compound as a brown oily liquid (138.8 g, 94.8% yield).
