Versuchsvorschrift

To a solution of 100 g (0.655 mol) 2-(5-ethyl-pyridin-2-yl)-ethanol in 500 mL acetic acid was added 118 g (1.049 mol) 30% hydrogen peroxide at 25-30° C. Reaction mixture was refluxed at 100° C. (tlc) for 14 hr. After completion of the reaction acetic acid was removed under vacuum, and the residual mass was poured in excess water and made alkaline by 10% Na2CO3 solution. Product was extracted with ethyl acetate and after concentrating ethyl acetate in vacuo, 89.58 g (81%) crystalline product was obtained.
