Reaction Steps

6.0 g N-benzoyl-N'-(4-methoxy-5-pyrimidyl)-thiourea are dissolved in 120 ml sodium ethylate solution (0.8 g sodium). After 1 hour, the solution is neutralized with diluted hydrochloric acid. The mixture is concentrated and the residue is washed with water and recrystallized from a methanol/water mixture. 2.3 g N-(4-methoxy-5-pyrimidyl)-thiourea having a melting point of 182° to 183° C. (decomp.) are obtained.
