Yield: 76%
Reaction Conditions:
with sodium hydroxide in ethanol;water
Steps:
19.l f
l) 2-Ethoxy-4-aminopyridine (Den Hertog, Kolder and Combe, 1951) 2-Bromo-4-aminopyridine (4 g). solid sodium hydroxide (4 g) and ethanol (15 ml) were heated in a bomb at 160° C. for 6 hours and allowed to cool. Water was then added and the solvent partially removed under reduced pressure. The mixture was then extracted with ether and the solvent removed, leaving a clear oil of 2-Ethoxy-4-aminopyridine (164 g, 76%) which slowly crystallized into colourless needles, m.p. 88-89° C.
