Versuchsvorschrift

A mixture of 4-(4-bromo-2-fluorophenylamino)-1-methyl-6-oxo-1,6-dihydropyridine-3-carboxylic acid (0.120 g, 0.352 mmol), EDCI (0.10 g, 0.53 mmol), and HOBt (0.071 g, 0.53 mmol) in DMF (5 mL) was stirred for 3 hours. O-(2-Vinyloxy-ethyl)-hydroxylamine (0.071 mL, 0.70 mmol) was added followed by Et3N (0.098 mL, 0.70 mmol). After 2 hours, the reaction mixture was diluted with EtOAc and washed with saturated NH4Cl solution, saturated NaHCO3 solution and brine. The organic layer was dried (MgSO4) and concentrated under reduced pressure. Purification by flash column chromatography (3% MeOH in methylene chloride) gave 0.078 g (52%) clean desired product.
