Reaction Conditions:
with lithium aluminium tetrahydride in tetrahydrofuran for 3 h;Reflux;
Steps:
(2-Aminopyridin-4-yl)methanol (1).
26 g of lithiumaluminum hydride was dissolved in 800 mL ofanhydrous THF. A solution of 103 g of methyl ether of2-aminoisonicotinate in 600 mL of anhydrous THFwas added at stirring and the formed slurry was boiledfor 3 h. After cooling water was carefully added, theprecipitate was filtered off and washed with 300 mL ofTHF. The combined filtrates were evaporated, theresidue was crystallized from benzene. Yield 61 g(73%), mp 80-81.5°. 1H NMR spectrum (DMSO-d6),δ, ppm: 4.36 s (2), 5.19 s (1), 5.78 s (2), 6.40 d(1), 6.46 s (1), 7.81 d (1). 13 NMR spectrum(DMSO-d6), δ, ppm: 62.3, 105.2, 110.3, 147.7, 152.7,160.3.
