Preparation of methyl alpha-D-glucopyranoside
10 ml of absolute methyl alcohol (free from acetone) placed in a flask, which is weighed together with a delivery tube, well cooled, so that no evaporation takes place, and dry hydrogen chloride passed in for a short time. The increase in weight is ascertained and the methyl alcohol diluted with the same solvent until it contains 0.25%, of hydrogen chloride. To 100 g of this dilute hydrogen chloride solution in methanol, 25 g of anhydrous and finely powdered D-glucose are added and boiled with reflux condenser for 45 minutes until the sugar is completely dissolved. The pale yellow liquid is converted into the glucoside on heating to 100° C by placing the solution in a sealed tube and heating for 50 hours in boiling water. The solution is then evaporated to one-third of its volume and well cooled. The methyl alpha-D-glucoside slowly deposits in small, colorless needles, which, after standing over night, are filtered and purified by crystallization from ethyl alcohol. The yield is about 45%.
