4-Methyl-6-ethyl-2-thiouracil, m.p. 211°,was prepared according to the directions of Johnson and Baily. 4-Methyl-6-ethyl-uracil, m. p.236°,was formed in a 81% yield from 4-methyl-6-ethyl-2-thiouracil by boiling the latter with an aqueous solution of monochloroacetic acid. 4-Methyl-6-ethyl-uracil reacted with phosphorous oxychloride and phosphorous pentachloride, giving 4-methyl-6-ethyl-2,6-dichloropy-rimidine in a 79% yield.
