Triethylamine → HCID 67324319, compound

Participants

Reaction Steps

2-Cyano-2-methylpropanehydrazide (100 mg, 0.78 mmol) and Et3N (0.1 mL, 0.86 mmol) were added to a solution of methyl benzimidate hydrochloride (100 mg, 0.58 mmol) in dry MeOH (10 mL), and the mixture was heated to reflux for 1 h. The reaction mixture was then concentrated under reduced pressure and the crude product was purified by column chromatography (silica 60-120 mesh, eluant 15% EtOAc in petroleum ether) to get 2-methyl-2-(3-phenyl-1H-1,2,4-triazol-5-yl)propanenitrile (80 mg, yield 51%). 1H NMR (300 MHz, MeOD) δ 7.98-7.95 (m, 2H), 7.52-7.50 (m, 3H), 1.82 (s, 6H). MS (ESI) m/z: Calculated for C12H12N4: 212.11. found: 213.2 (M+H)+.
