Reaction Steps

To a mixture of 1.25 mL (10.5 mmol) tert-butyl nitrite and 1.42 g (10.5 mmol) copper(II)chloride in 40 mL acetonitrile was added a solution of 1.20 g (6.59 mmol) 4-amino-6-methoxy-pyridine-2-carboxylic acid methyl ester in 10 mL acetonitrile dropwise at 40° C. This mixture was stirred at 80° C. for 1 h, then poured into ice water, acidified with 4 M aqueous HCl and extracted with EtOAc. The combined organic phases were dried over sodium sulfate, filtered and concentrated in vacuo. The crude material was purified by flash chromatography (PE/EtOAc=3/1→2/1).
