The condensation of thiourea with ethyl methyl-acetoacetate in the presence of sodium ethylate in absolute ethyl alcohol gives 2-thio-4,5-dimethyl-6-oxy-pyrimidine,m.p.279-280°,which is ethylated to form 2-ethylmercapto-4,5-dimethyl-6-oxy-pyrimidine,m.p.155-156° by treating the former with ethyl iodide in the presence of sodium ethylate in absolute alcohol.
