Reaction Conditions:
with palladium 10% on activated carbon;hydrogen in ethanol;toluene at 25; under 1500.15 Torr; for 4 h;Autoclave;
Steps:
4
A toluene solution (331 g) of the obtained 2-amino-5-benzyloxypyridine,Ethanol (217 g) and 10% Pd / C (2.28 g, moisture content 53%) were charged in an autoclave and reacted at 25 ° C. for 4 hours while being introduced at 0.2 MPa (absolute pressure) in a hydrogen atmosphere.After completion of the reaction, Pd / C was filtered and the residue was washed with ethanol (76 g).The filtrate was dried under reduced pressure to obtain 2-amino-5-hydroxypyridine (25.6 g, 0.23 mol) (yield 92%).
