実験手順

A mixture of 2.00 g (10.9 mmol) 1-allyloxy-4-chloromethyl-benzene and 917 mg (12.1 mmol) thiourea in 3.0 ml ethanol was heated to reflux for 7 h. Solvents were distilled off and the crystalline residue was washed with cold ethanol and isolated by filtration. After addition of 2.5 ml ethanol, 1.0 ml water and 0.7 ml 25% aqueous ammonia, the mixture was heated to reflux for 1 h. Ethanol was distilled off, then acidified with 0.5 ml half conc. HCl and extracted with ethyl acetate. The solution was dried over MgSO4 and solvents were removed in vacuo to yield 1.59 g (81%) colourless oil, which was used immediately.
