Procedure
A mixture of 1-(2-chlorophenyl)methyl thiourea (3 g, 14.9 mmol) and propylbromide (13.5 g, 110 mmol) in acetonitrile (20 mL) was refluxed for 5 hours. The solvent was evaporated, the residue was dissolved in 200 mL of 50% water/ether and acidified with 48% hydrobromic acid solution. The two phases were separated, the aqueous layer was washed with ether and then the aqueous layer was basified with 10% sodium carbonate solution. The liberated product was extracted with diethyl ether, washed with water and brine, dried and concentrated to give 1-(2-chlorophenyl)methyl-2-propyl-2-thiopseudourea (2.82 g, 78%); mp 112°-114° C.
