Reaction Steps

N-butyl-N-(2-chloro-2-propenyl)-N'-phenylthiourea (0.26 g) was added to 90% sulfuric acid (2.5 g) at room temperature with stirring, and the mixture was heated to 50° C. and stirred at the same temperature for 1.5 hour. After cooling, water was added to the reaction mixture, which was then neutralized by addition of sodium hydrogen carbonate and extracted with ethyl acetate. The organic layer was washed with water. The solvent was removed by distillation under reduced pressure, which afforded 0.09 g of 2-(N-phenylimino)-3-butyl-5-methyl-4-thiazoline as an oil (34% yield).
