Reaction Steps
Dimethyl sulfate (195 grams) was added to a mixture of 2-((4R,6S)-6-(hydroxymethyl)-2,2-dimethyl-1,3-dioxan-4-yl)acetic acid (200 grams), methanol (800 ml) and sodium bicarbonate (50 grams) at 0° C. and stirred for 12 hours at 25-30° C. After completion of the reaction, reaction mixture was quenched with water and extracted into methylene chloride. The methylene chloride was distilled off from the reaction mixture under reduced pressure to get the title compound.
