Reaction Steps
S-Methylisothiourea (22.26 g, 160 mmol) was added to a solution of sodium carbonate (16.9 g, 160 mmol) in water (50 mL) and stirred at room temperature until complete dissolution of the S-methylisothiourea. Ethyl acetoacetate (10.41 g, 80 mmol) was added to the mixture in one portion. After stirring for 60 hours at room temperature, the reaction was neutralized with acetic acid precipitating a white solid. The solid was collected, washed with water, and dried in vacuo to give 4-hydroxy-6-methyl-2-(methylthio)pyrimidine (9.38 g, 75%), m.p. 218-221° C.
