1-[(4-chlorobenzoyl)amino]-1,3-dimethylthiourea

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The 1:1 mixture of 1-(4-chlorobenzoyl)-2,4-dimethylthiosemicarbazide and pyridine hydrochloride (3.61 g of mixture) from Example 2 and 1 molar aqueous NaHCO3 (100 ml, 1.00×10-1 mole) were stirred and warmed to reflux. After refluxing for 5 hours the reaction was allowed to cool. It was then placed in a refrigerator for several hours before the precipitate was collected by filtration. The collected material was dried partially by suction before being transferred to a desiccator where it was dried at high vacuum. This affords the desired product as a beige powder: 2.01 g (84%). This was purified by flash chromatography and subsequent crystallization from isopropanol yielding small, slightly yellowish plates: 1.74 g (73%), mp 113°-115° C. warmed to reflux After refluxing for 5 hours the reaction to cool It was then placed in a refrigerator for several hours before the precipitate was collected by filtration The collected material was dried partially by suction before being transferred to a desiccator where it was dried at high vacuum
