Reaction Steps

A 1.18 g portion of 2,5-anhydro-3,4,6-tris-O-(phenylmethyl)-D-mannose was dissolved in 8.5 ml of methanol, treated with 5.11 ml of 37% formalin and 480 mg of potassium carbonate and the mixture immersed in an 85° C. bath. After 4 hours the mixture was cooled, neutralized with 3.5 ml of 10% sulfuric acid and the volatiles removed. The residue was extracted with chloroform, giving 0.86 g of the desired compound after chromatography.
