YieldReaction ConditionsOperation in experiment
43%
Stage #1: With water; sodium hydroxide In ethanol at 20℃; for 3 h;
Stage #2: With hydrogenchloride In ethanol; water
2M Aqueous sodium hydroxide solution (1.91 mL, 3.8 mmol) was added to a stirred solution of ethyl 5-bromo-6-methylnicotinate (preparation 47c, 0.41 g, 1.7 mmol) in ethanol (14 mL) at room temperature.
After 3 hours, the solvent was evaporated and water was added to the residue.
The pH was adjusted to 4-5 with concentrated hydrochloric acid and the mixture was extracted with ethyl acetate.
The organic layer was washed with water, dried (MgSO4) and evaporated to give the title compound (0.16 g, 43percent) as a white solid.
LRMS (m/z): 216/218 (M+1)+.

YieldReaction ConditionsOperation in experiment
45% With potassium carbonate In 1,4-dioxane at 110℃; for 72 h; Inert atmosphere An oven-dried resealable Schlenk tube was charged with ethyl 5,6-dibromonicotinate (preparation 47b, 1.09 g, 3.5 mmol), methylboronic acid (0.24 g, 4.0 mmol), potassium carbonate (1.46 g, 10.6 mmol) and 1,4-dioxane (27 mL).
The Schlenk tube was subjected to three cycles of evacuation-backfilling with argon, and then tetrakis(triphenylphosphine)palladium(0) (0.41 g, 0.35 mmol) was added.
After three new cycles of evacuation-backfilling with argon, the Schlenk tube was sealed and the mixture was stirred and heated in an oil bath to 110 °C.
After 3 days, the mixture was cooled, filtered through Celite.(R). and the filtrate was evaporated.
Purification of the residue by flash chromatography (97:3 to 9:1 hexanes/ethyl acetate) gave the title compound (0.41 g, 45percent) as a solid.
LRMS (m/z): 244/246 (M+1)+.
1H-NMR δ (CDCl3): 1.41 (t, J=9.0Hz, 3H), 2.74 (s, 3H), 4.41 (q, J=9.0Hz, 2H), 8.40 (d, J=3.0Hz, 1H), 9.01 (d, J=3.0Hz, 1H).
