실험 절차

10 g of 5-amino-1-β-D-ribofuranosyl-4-imidazolecarbonitrile was dissolved in 20% ammonia methanol solution. 10 ml of acetonitrile was added thereto and the solution was heated for 5 hours at 180° C. The solvent was distilled off, purified by silica gel column chromatography and recrystallized from methanol to give 4.2 g of 2-methyladenosine (yield: 35.9%). 2-methyladenosine was methylated in the same manner as the above-mentioned [METHOD 1] to give Compound 5 and Compound 6.
