実験手順
A mixture of methyl 2-((4R,6S)-6-(hydroxymethyl)-2,2-dimethyl-1,3-dioxan-4-yl)acetate (110 grams) and n-butylamine (370 grams) was heated to reflux and stirred. After completion of the reaction, the reaction mixture was distilled under reduced pressure. Water (500 ml) was added to the obtained residue followed by sodium bicarbonate and washed it with petroleum ether. The reaction mixture was extracted into methylene chloride. The solvent from the reaction mixture was distilled off under reduced pressure to get the title compound.
