Reaction Steps

A mixture of 5-(5-chlorothiophen-2-yl)-2-(4-fluoro-phenyl)-4-hydroxymethyloxazole (1.44 g) and manganese dioxide (4.76 g) in tetrahydrofuran (20 ml) was refluxed for 3 hours. The reaction mixture was filtered through Cellite and the filtrate was concentrated under reduced pressure. The resulting reside was triturated with diethyl ether to obtain 5-(5-chlorothiophen-2-yl)-2-(4-fluorophenyl)-4-formyl-oxazole (943 mg) as colorless powder.
