実験手順
5 g of D-Ribose was dissolved in 100 mL of methanol and cooled to 0° C. 0.5 mL of concentrated sulfuric acid was added and the solution was stored at −20° C. for 48 hrs. Solution was neutralized by passage through a bed of sodium carbonate and evaporated under vacuum to a viscous oil. Crude material was purified on a silica column eluting with 10% methanol in ethyl acetate to yield 2.1 grams of methyl β-D-ribofuranoside.
