EXAMPLE 1; Step A:; A solution of NaOCl (1.2 L, of 5%) was cooled to 0 0C in ice bath. 2-hydroxy-6- methylpyrridine-3-carboxylic acid 1-1 (100 g, 0.65mol) was added in small portions. The resulting homogenous mixture was stirred at 0 0C for 1 hour and then at 1O0C for 5 hours. Another portion NaOCl(300 mL, of 5%) was added at O0C and the mixture was stirred at 100C overnight. The solution was acidified to pH = 1 with 12N HCl, and the resulting solid was filtered, washed with water, and oven dried to afford white solid product 1-2 (m/z (ES) (M+H)+= 188).
