Yield:213771-32-5 83%

Reaction Conditions:

with potassium carbonate in N,N-dimethyl-formamide at 80; for 0.666667 h;

Steps:

90.C methyl 5-bromo-3-methylpyridine-2-carboxylate
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 (83% yield) of the desired product as a yellow solid.
