Versuchsvorschrift

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of 1-(2-bromo-thiazol-5-yl)-ethanol (1.95 g, 9.37 mmol) in AcCN (90.0 mL) was treated at rt with MnO2 (4.53 g, 46.86 mmol) and the reaction mixture was stirred for 16 h at rt before being filtered through Celite. The solvent was removed under reduced pressure to give the title compound as a yellow solid. LC-MS-conditions 02: tR=0.80 min.
