Procedure
In a 250 mL round-bottom flask with a stir bar was charged 2-chloromethylacetate (17.5 mL, 0.2 mol), ethyl acetate (50 mL), and pyridine (16.2 mL, 0.2 mol). The overall homogeneous solution was heated with a condenser at 80° C. for 24 h and the resulting heterogeneous white suspension was cooled to room temperature and filtrated under reduced pressure. The off-white filtrate was recrystallized from small amount of ethanol to give the title compound (27.4 g, 73%) as a white solid. MS (ES+): 152 (M)+.
