YieldReaction ConditionsOperation in experiment
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).

YieldReaction ConditionsOperation in experiment
With sodium hydroxide; In water; PREPARATION 54 5-Chloro-2-hydroxy-6-methyl-3-pyridinecarboxylic acid To a solution of 15.7 g of 50% sodium hydroxide and 18.2 ml of water was added 10 g (0.065 mole) of <strong>[38116-61-9]2-hydroxy-6-methylnicotinic acid</strong>. When the acid had dissolved, 200 ml of 5.25% aqueous sodium hypochlorite was added rapidly through a dropping funnel. The temperature was not moderated (slight exotherm did occur). The entire mixture was stirred at room temperature for 18 hr. The reaction mixture was then filtered and acidified with concentrated hydrochloric acid. The precipitate was recrystallized from isopropyl alcohol/ethereal to give ~6 g of analytically pure crystals, m.p. 291-94 C. Analysis: Calculated for C7 H6 NO3 Cl: C, 44.82; H, 3.22; N, 7.47. Found C, 44.69; H, 3.17; N, 7.45.
