NaH (53 mg, 2.2 mmol) was suspended in dry THF (1.5 ml) under a stream of N2 and 3-bromo-benzenethiol (378 mg, 2 mmol) was added dropwise to the suspension over 5 min. 4-Chloromethyl-2-phenyl-thiazole (419 mg, 2 mmol) was added and the solution left stirring overnight. The reaction mixture was quenched with a saturated K2CO3 solution (8 ml) and extracted with EtOAc (3×4 ml). The combined organic layers were washed with saturated K2CO3 solution (4 ml), dried (MgSO4), filtered and the solvent removed in vacuo. The residue was purified by column chromatography eluting with 20% EtOAc in heptane to give the title compound.
