Versuchsvorschrift

The crude 2-[2-(6-Chloro-pyridin-3-yl)-5-methyl-oxazol-4-yl]-ethanol from step C is dissolved in methylene chloride (50 mL), then TsCl, DMAP and triethyl amine are added and stirred overnight. The reaction mixture is washed with water, brine and concentrated. Column chromatography on silica gel gave the title compound (0.5 g).
