Procedure

Dissolve 2-cyano-3-fluoropyridine (300 mg, 2.457 mmol) in absolute ethanol (12 mL). Add 10% Pd/C (93 mg) and concentrated HCl (0.614 mL, 7.37 mmol). Hydrogenate at 40 psi overnight. Filter through Celite® and concentrate in vacuo to give the title compound as a solid (440 mg, 90%). MS (ES+) M/z: 127 (M+H)+.
