Procedure

2-Aminonicotinic acid (0.912 g, 6.6 mmol) was dissolved in 90% methanol (137 ml) and conc. HCl (3.5 ml, 40 mmol) was added. The solution was hydrogenated over PtO2 (200 mg) in a Parr shaker apparatus at room temperature and 29 psig for 2 hours. Filtration and evaporation gave 1.22 g (100%) oily product identified by ir 3300-2500, 1724 cm-1.
