1H-1,2,4-Triazole → (+/-)-N-[4-[2-methyl-1-(1H-1,2,4-triazol-1-yl)propyl]phenyl]acetamide

Participants

Reaction Steps

A mixture of (±)-4-(acetylamino)-α-(1-methylethyl)benzenemethanol methane sulfonate (ester) (0.1541 mol), 1H-1,2,4-triazole (0.308 mol) and K2CO3 (0.308 mol) in CH3CN (500 ml) was stirred and refluxed for 12 hours. The solvent was evaporated and the residue was taken up in water/CH2Cl2. The organic layer was dried, filtered off and the solvent evaporated. The residue was purified by column chromatography over silica gel (eluent: CH2Cl2/CH3OH 97/3). The pure fractions were collected and evaporated, yielding 10 g (25%) of (±)—N-[4-[2-methyl-1-(1H-1,2,4-triazol-1-yl)propyl]phenyl]acetamide (compound 153).
