Participants

Reaction Steps

Add concentrated HCl (0.46 mL) to a suspension 2-fluoro-nicotinonitrile (0.34 g, 2.8 mmol) and 5% Pd/C (0.5 g) in methanol (10 mL) at RT. Stir suspension under an atmosphere of hydrogen at 1 atm. For 6 hours. Filter reaction mixture and concentrate the filtrate. Add ether to the residue, bubble HCl gas through the suspension, filter precipitate, and dry to give the title compound (0.37 g, 82%).
