HCID 227274305-Amino-2-(dimethylamino)isonicotinic acidYield 98.8%

Procedure

2-(N,N-Dimethylamino)-5-(2,2-dimethylpropionamido)-pyridine-4-carboxylic acid (0.8 g) was treated with 5N HCl at reflux for 5 hours. The mixture was allowed to cool and evaporated to dryness to give the title compound (0.54 g);δH [2H6]DMSO 8.15(1H,s), 7.35(2H,bs), 6.70(1H,s), 3.10(6H,s); m/z (M+1+)182.
