실험 절차

4-Carboxy-3-(2-methoxypyrimidin-5-yl)butanoic acid (11.5 kg) was treated with trifluoroacetic anhydride (12.1 kg) in THF (58 L) at 50-55° C. for several hours. Slow addition of heptane (195 L) followed by cooling to ambient temperature resulted in the crystallization of the title compound; 94% yield.
