Versuchsvorschrift

Heated a reaction mixture of 4-(benzyloxy)-1-(3-fluorobenzyl)pyridin-2(1H)-one (4.83 g, 15.6 mmol) in anhydrous acetonitrile (55 mL) and N-iodosuccinimide (NIS, 3.86 g, 17.1 mmol) under nitrogen atmosphere at 65° C. for 4 h. The reaction mixture was concentrated under reduced pressure and the residue was purified by flash chromatography (silica gel) using EtOAc/hexanes (1:1 v:v). The appropriate fractions were collected according to ES MS (M+H 436) and washed with Na2SO3 to remove the color impurities. The fractions were concentrated under reduced pressure and dried in vacuo to afford the desired product (6.15 g, 90%) as a light yellow solid.
