Sodium Hydroxide → 3-(4-Methoxybenzylmercapto)-4-n-butyl-1,2,4-triazole

Participants

Reaction Steps

To a mixture of 10 g. (0.064 mole) of 3-mercapto-4-n-butyl-1,2,4-triazole and 2.6 g. (0.064 mole) of sodium hydroxide in 200 ml. of methanol was added 9.9 g. (0.064 mole) of p-methoxybenzyl chloride. The reaction mixture was heated at reflux about 20 hours. The solvent was evaporated off, the residue washed with water, dried and distilled. There was obtained 17.8 g. of yellow liquid distilling at 190°-205° C. at 0.03 mm. Nuclear magnetic resonance and ultraviolet spectra indicated this to be approximately an equal mixture of 3-(4-methoxybenzylmercapto)-4-n-butyl-1,2,4-triazole and 4-n-butyl-2-(4-methoxybenzyl)-1,2,4-triazoline-3-thione.
