Reaktionsschritte

4-Carboxy-2-acetylaminopyridine (3.4 g, 19 mmol) was dissolved in methanol/benzene (100 mL, 1:1). TMS-diazomethane was added (1M, Aldrich) with cooling until the yellow color just persisted, then the solvent was removed under reduced pressure. The product was purified by silica gel column chromatography (50/50 hexane/ethyl acetate) and 3.0 g of product was recovered.
