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. |
82% | With potassium carbonate In N,N-dimethyl-formamide at 80℃; for 0.666667 h; | Example 11.1: methyl S-bromo-S-metliylpyridine-Z-carboxylateO; To a solution of 5-bromo-3-methylpyridine-2-carboxylic acid (450 mg, 2.08 mmol) in dimethylformamide (2 mL) was added potassium carbonate (862 mg, 6.24 mmol) and iodomethane (739 mg, 5.21 mmol) and the reaction was stirred at 80 0C for 40 min. The reaction mixture was partitioned with ethyl acetate and water and the organic layers were washed with brine, dried over sodium sulphate, filtered and concentrated to afford the product as a yellow solid (380 mg, 82percent). 1H NMR (300 MHz, CDCl3): δ 8.91 (s, IH), 7.86 (s, IH), 3.98 (s, 3H), 2.60 (s, 3H). |

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. |
