Reaction Steps

The first intermediate, 4,6-dihydroxy-2-10 methylpyrimidinamine, is synthesized by preparing sodium ethoxide in situ from sodium and an hydrous ethanol under a nitrogen blanket. Acetamidine hydrochloride and diethyl malonate are added and the reaction mixture heated to boiling for 2 to 5 hours to afford 4,6-dihydroxy-2-methylpyrimidine.
