YieldReaction ConditionsOperation in experiment
With hydrogenchloride; sodium hypochlorite; In tetrahydrofuran; b) To a mixture of 100 ml of 25% aqueous hydrochloric acid and 250 ml of DCM was added 18 g of 5-methyl-2-thio-pyridine. While the mixture was vigorously stirred and kept at -1 0 C. 250 ml of an aqueous solution containing 13% of sodium hypochlorite was carefully added. Upon completion of the addition, stirring was continued for 10 min. The organic layer was separated. To the aqueous layer 250 ml of DCM was added and the mixture was again treated as before with a further 250 ml batch of bleach. Upon completion of the addition, the organic layer was separated. The aqueous layer was extracted five times with 200 ml DCM. The organic layers were combined, dried over MgSO4 and evaporated. The resulting oil was dissolved in 125 ml of THF and cooled to -20 C. 25 ml of saturated aqueous ammonium hydroxide solution was slowly added. The mixture was stirred over night at room temperature. Excess of ammonia was neutralised by adding hydrochloric acid and the THF was removed in vacuo. The remaining aqueous solution was extracted three times with 150 ml of ethyl acetate. The combined organic layers were dried over MgSO4 and the solvent was evaporated. The remaining solid was recrystallized from boiling ethyl acetate to yield 13.35 g of 5-methyl-2-pyridine sulfonamide in form of beige crystals. 1H-NMR(D6-DMSO, 300 MHz): 2.37(s, 3H); 7.36(s, 2H); 7.78-7.85(m, 2H); 8.53(s, 1H); LC-MS: tR=2.32 min, [M+1]+=173.04, [M-1]-=171.10.
