Versuchsvorschrift

A mixture of acetic anhydride (8.54 mL, 24.63 mmol) and formic acid (12.8 mL, 24.63 mmol) was stirred at room temperature for 40 min. To this mixture 6-bromo-2-methoxypyridin-3-amine (5.000 g, 24.63 mmol) in 30 mL of THF was added dropwise. The resulting solution was heated at 60° C. with stirring for 16 h. Upon cooling, the reaction mixture was poured into icewater. The resulting precipitate was filtered to give N-(6-bromo-2-methoxypyridin-3-yl)formamide (5.690 g, 24.63 mmol, 100% yield) as light brown solid. LC-MS (M+Na)+=231.0.
