YieldReaction ConditionsOperation in experiment
Step 2-Preparation of 2,6-difluoro-nicotinic acid methyl ester (52)In a round bottom flask, 2,6-difluoro-nicotinic acid (51, 5.60 g, 35.2 mmol), 60.0 mL of methanol and sulfuric acid (1.0 mL, 19.0 mmol) are combined and heated to reflux overnight. The reaction is poured into water, adjusted to pH around 9 with 1M aqueous potassium carbonate, and extracted with ethyl acetate. The organic layer is dried over sodium sulfate, filtered and the filtrate concentrated under vacuum to provide the desired compound as a yellow oil (52, 3.5 g).
