Procedure

[R-(R*, R*)]-α-(1-Formyl-2-hydroxyethoxy)-3,4-dihydro-2,4-dioxo-1(2H)-pyrimidineacetaldehyde, (uridinedialdehyde), (2.42 g) was dissolved in a mixture of methanol (50 ml) and water (50 ml). To the solution was added 2-amino-1,3,4-thiadiazole (1.00 g). The mixture was stirred at ambient temperature for four hours and evaporated in vacuo. The residue was triturated with acetone to give 1-[(2R, 6R)-3,5-dihydroxy-6-hydroxymethyl-4-(1,3,4-thiadiazol-2-yl)morpholin-2-yl]-uracil (3.0 g).
