실험 절차

[R-(R*, R*)]-α-(1-Formyl-2-hydroxyethoxy)-3,4-dihydro-2,4-dioxo-1(2H)pyrimidineacetaldehyde, (uridinedialdehyde), (4.0 g) was dissolved in a mixture of methanol (30 ml) and water (30 ml). To the solution was added 3-amino-5-methylisoxazole (1.62 g). The mixture was stirred at ambient temperature for five hours and evaporated in vacuo. The residue was triturated with acetone to give 1-[(2R, 6R)-3,5-dihydroxy-6-hydroxymethyl-4-(5-methylisoxazol-3-yl)morpholin-2-yl]uracil (4.2 g).
