Reaction Steps

A mixture of intermediate 1 (37.2 g) and sodium methylate (36 g) in methanol (250 ml) was stirred for 30 min. Ethane iodide (31.2 g) was added dropwise. The reaction mixture was stirred and refluxed for 3 hours. The solvent was evaporated and the residue was stirred in water, filtered and recrystallized from CH3CN. The precipitate was filtered off and dried, yielding 26 g (60%) of 2-(ethylthio)-5-(2-hydroxyethyl)-6-methyl-4(3H)-pyrimidinone (intermediate 2).
