YieldReaction ConditionsOperation in experiment
83% With potassium carbonate In N,N-dimethyl-formamide at 80℃; for 0.666667 h; Step C
methyl 5-bromo-3-methylpyridine-2-carboxylate
To a solution 5-bromo-3-methylpyridine-2-carboxylic acid (2.6 g, 12 mmol) in N,N-dimethylformamide (20.0 mL) was added potassium carbonate (4.99 g, 36.1 mmol) and methyl iodide (1.50 mL, 24.1 mmol) and the reaction was stirred 80° C. for 40 min.
The reaction mixture was partitioned with EtOAc and water.
The organic layers were washed with brine, dried over sodium sulfate, filtered and concentrated to afford 2.3 g (83percent yield) of the desired product as a yellow solid.

YieldReaction ConditionsOperation in experiment
99% With thionyl chloride In methanol for 6 h; Reflux To a mixture of 5-bromo-3-methylpicolinic acid (600 mg, 2.8 mmol) in MeOH (10 mL) was added 50C12 (397 mg, 3.3 mmol). The mixture was stirred at reflux temperature for 6 hours. LCMS showed the reaction was complete. The reaction mixture was evaporated in vacuo to afford methyl 5-bromo-3-methylpicolinate (640 mg, 99percent yield), m/z = 229.76(M+H), as an off-white solid.

YieldReaction ConditionsOperation in experiment
98% With water; sodium hydroxide In ethanol at 80℃; for 1.5 h; Step B
5-bromo-3-methylpyridine-2-carboxylic acid
To a solution of 5-bromo-3-methylpyridine-2-carbonitrile (3.9 g, 20 mmol) in ethanol (30 mL) was added 6.0 M sodium hydroxide in water (15 mL), and the reaction was stirred at 80° C. for 1.5 h.
The reaction mixture was concentrated, diluted with water and partitioned in EtOAc.
The aqueous phase was acidified to pH 2-3.
The product then was extracted with EtOAc, washed with brine, dried over sodium sulfate, filtered and concentrated to give 4.2 g (98percent yield) of the desired product as a yellow solid.
98%
Stage #1: at 80℃; for 1.5 h;
Stage #2: Acidic aqueous solution
Example 10.1: 5-bromo-3-methylpyridine-2-carboxylic acid; To a suspension of 5-bromo-3-methylpyridine-2-carbonitrile (1.22 g, 7.21 mmol) in ethanol (10 mL) was added 6N sodium hydroxide (5 mL) and the reaction was stirred at 80 <n="35"/>0C for 1.5 h. The organic was concentrated and the reaction mixture was dilute with water and partitioned in ethyl acetate. The aqueous phase was acidified to pH 2-3. The product was extracted with ethyl acetate, washed with brine, dried over sodium sulphate, filtered and concentrated to afford the product as a yellow solid (185 mg, 98percent). 5H NMR (300 MHz, CDCl3): δ 8.54 (bs, IH), 7.90 (s, IH), 2.76 (s, 3H).
