Versuchsvorschrift
Manganese (IV) dioxide (1.599 g) was added to a solution of 2-(2-chloro-3-(hydroxymethyl)phenyl)ethanol (example 80, step c) (0.342 g) in DCM (20 mL), and the resulting suspension was stirred at room temperature overnight. The mixture was then concentrated onto silica and purified by flash chromatography on silica eluted with 25% ethyl acetate in isohexane to afford the subtitled compound as a white crystalline solid. Yield 0.223 g.
