Participants

Reaction Steps

To a solution of 16.8 g. (0.2 mole) of sodium bicarbonate in 300 ml of water was added 22.8 g.(0.2 mole) of 6-methyl-2-thiouracil. The mixture was heated on a steam bath for 10 minutes. To this mixture was then added 18.6 g.(0.2 mole) of 2-chloroacetamide followed by 100 ml of absolute ethanol. The mixture was heated on a steam bath for 2 hours. The solution was cooled in an ice bath and the precipitate which formed was collected and recrystallized from a mixture of N,N-dimethylformamide and ethanol to afford 8 g. of product, m.p. 238°-240° d.
