Reaction Steps
A mixture of 3,5-difluoropicolinonitrile (1.4 g, 10 mmol), conc. HCl (12 ml) and 10% Pd—C (200 mg) in 1:1 ethanol/tetrahydrofuran was shaken under a hydrogen atmosphere (50 psi) for 5 h. The reaction mixture was filtered and the ethanol removed in vacuo. The remaining solution was lyophilized to afford an off-white solid (2.16 g, 100% yield). LCMS (M+H) calcd for C6H7F2N2: 145.06; found: 145.12.
