3-Chloro-2-fluorobenzyl bromide (1.00 g) and thiourea (0.35 g) were heated together at reflux in ethanol (10 ml) for 1 hour. The solvent was removed in-vacuo and the residue was suspended in 10% aqueous sodium hydroxide (10 ml) and heated at reflux for 3 hours. The solution was then acidified with conc. HCl and extracted into ether. Concentration of the organic phase in-vacuo gave the subtitle compound as a pale yellow oil (0.71 g).
