Reaction Steps

2-Amino-5-methoxy-pyridine. A mixture of 2-amino-5-iodo-pyridine (1 g, 4.54 mmol) in 20 mL of absolute methanol with 400 mg of copper powder and sodium methoxide (6 mmol) was heated at 160° C. overnight in a seal tube. The reaction mixture was cooled to room temperature, diluted with 80 mL of methanol and filtered through a pad of celite. The filtrate was concentrated and the residue was purified by chromatography (80% ethyl acetate/hexane) to give the title compound (174 mg, 31%). 1H NMR (CDCl3): 7.78 (d, J=2.7, 1H), 7.09 (dd, J=3.0, 9.0, 1H), 6.48 (d, J=9.0, 1H), 3.78 (s, 3H).
