Yield:-
Reaction Conditions:
with bromine;sodium acetate in acetic acid at 20 - 80;
Steps:
10.1
Step 1: To 5-bromo-2-methoxypyridine (0.564 g, 3.0 mmol) and sodium acetate (0.246 g, 3.0 mmol) in acetic acid (3 mL) was added bromine (0.27 mL, 5.25 mmol), and the mixture was stirred at 80° C. for 3 hours, and then at room temperature overnight. The mixture was diluted with H2O and extracted with EtOAc, and the combined organic layers were washed with saturated aqueous Na2CO3 and saturated aqueous Na2S2O3. The organic layer was concentrated and dried under high vacuum to give 3,5-dibromo-2-methoxy-pyridine.
