Versuchsvorschrift

To a stirred solution of 6-bromo-3-pyridinol (10 g, Commercial eg Apollo Scientific Ltd.) in DMF (100 ml) was added potassium carbonate (17.8 g). The reaction mixture was stirred for 15 min at 25-30 C. before cooling to 15° C. To this was added slowly benzyl bromide (7.5 ml) and this was stirred at 25-30° C. for 48 h. The reaction mixture was poured into cold water and the solid was collected by filtration to give the title compound, 14.5 g
