Methyl iodide → 3-(4-Methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)pyridine

Participants

Reaction Steps

MeI (2 mL, 32 mmol) in EtOH (10 mL) was added to a mixture of 4-methyl-5-pyridin-3-yl-2,4-dihydro-3H-1,2,4-triazole-3-thione in 1 M NaOH (70 mL, 70 mmol). After 1 h stirring at r.t., DCM was added and the layers were separated. The water phase was washed with DCM and the combined organic phases were dried and concentrated to give 6.5 g (98%) of the title compound. 1H NMR: 2.76 (s, 3H) 3.59 (s, 3H) 7.43 (m, 1H) 7.99 (m, 1H) 8.71 (m, 1H) 8.86 (m, 1H)
