Versuchsvorschrift

Add manganese dioxide (4.4 g, 50.6 mmol) to a solution of N-(tert-butoxycarbonyl)-2-fluoro-4-(1-hydroxy-3,3-dimethyl-butyl)-benzylamine (1.1 g, 3.38 mmol) in anhydrous 1,4-dioxane (45 mL) at room temperature. Heat the reaction mixture at 70° C. overnight. Filter the reaction mixture over Celite® and concentrate in vacuo. Purify by chromatography on silica gel eluting with hexane/EtOAc (9:1) to obtain the desired intermediate as an oil (980 mg, 90%).
