Reaction Steps

67 g (0.46 mol) of 5-cyanopyridine-2-carboxamide (Chem. Ber. 117 (1984) 1259) were suspended in 1 l aqueous methanol (1/1) and 84.7 ml (1.9 equivs.) of conc. HCl, 21,4 g of 10% strength Pd/C were added and hydrogenation was carried out in a shaken vessel at room temperature for 5 h (H2 uptake: 23.2; l theory: 22.3 l). The product dissolved during the hydrogenation (and the catalyst changed from gray to black). TLC (CH2Cl2/MeOH 9/1, NH3-saturated) revealed only traces of starting material.
