Reaction Steps
To a solution of 2-aminonicotinic acid (20.5 g, 148.1 mmole) in THF was added lithium aluminum hydride (300 mL, 1.0 M in THF) over 30 minutes. The reaction solution was heated to reflux for 18 hrs and then was cooled to room temperature. The reaction was quenched by the sequential dropwise addition of H2O (11.5 mL), 15% NaOH (11.5 mL), and H2O (34.5 mL). The mixture was stirred for 15 min, then was filtered through Celite®, and the filter pad was washed thoroughly with THF followed by 5% CH3OH/CHCl3. The filtrate was concentrated to give the title compound (15.24 g, 83%) as a waxy light yellow solid: MS (ES) m/e 125 (M+H)+.
