Procedure
To a solution of 1-[2-(4-Chlorophenyl)thiazol-5-yl]ethanol (129 mg, 0.54 mmol) and 4-chloro-1-methyl-8-oxabicyclo[3.2.1]oct-3-en-2-one (93 mg, 0.54 mmol) in dry THF (5 ml) is added in one portion the sodium hydride, 60% dispersion in mineral oil, (21 mg, 0.54 mmol). The reaction mixture is stirred at room temperature overnight. Silica gel is added to the crude reaction mixture, and the solvent is evaporated under reduced pressure. The residue is purified by flash chromatography on silica gel to give 4-{1-[2-(4-Chlorophenyl)thiazol-5-yl]-ethoxy}-1-methyl-8-oxabicyclo[3.2.1]oct-3-en-2-one (160 mg).
