Stage #1: With n-butyllithium In hexanes; diethyl ether at -70 - -40℃;
Stage #2: at -70 - 20℃;
Stage #3: With hydrogenchloride In water
Preparation C4:
Synthesis of 6-(trifluoromethyl)picolinic Acid
Preparation C4, Step 1: 2-bromo-6-(trifluoromethyl)-pyridine (100 mg, 0.44 mmol, 1 eq.) was dissolved in diethyl ether at room temperature under nitrogen then cooled to -70° C. Added 1.6M n-Butyllithium in hexanes (0.28 mL, 0.44 mmol, 1 eq.) dropwise via an addition funnel.
Stirred at -40° C. for 15 minutes then cooled to -70° C. and bubbled in CO2 gas for 10 minutes.
Allowed to warm to room temperature.
Added water then rinsed 3 times with diethyl ether.
The aqueous pH was adjusted to=3 with conc. HCl.
Extracted the acidic aqueous layer 3 times with ethyl acetate.
The ethyl acetate layers were combined, dried over sodium sulfate and stripped to give 6-(trifluoromethyl)picolinic acid (30 mg) as a white solid. Yield=35percent. LCMS detects (M+H)+=192.06.

YieldReaction ConditionsOperation in experiment
67% at 60℃; for 18 h; Inert atmosphere Step 1:
Methyl 6-trifluoromethyl-pyridine-2-carboxylate
Under the protection of nitrogen gas, to a solution of 2-bromo-6-trifluoromethylpyridine (1.48 g, 6.55 mmol) in methanol (50.0 mL) were successively added palladium acetate (74.0 mg, 0.33 mmol), 1,1'-bis(diphenylphosphino)ferrocene (363.0 mg, 0.655 mmol) and triethylamine (0.92 g, 9.8 mmol), and reacted at a temperature of 60 °C for 18 hours under carbon monoxide atmosphere (2 atm).
After the reaction was complete, the reaction solution was cooled to room temperature, and filtered.
The filtrate was concentrated in vacuo, and the resulting residue was purified by column chromatography on silica gel to afford methyl 6-trifluoromethyl-pyridine-2-carboxylate (0.9 g, yield 67.0percent).
