3-Ethyl-1-pentyn-3-ol → 7-{[4-(1-ethyl-1-hydroxypropyl)-1H-1,2,3-triazol-1-yl]methyl}-4-phenylquinoline-2-carbonitrile

Participants

Reaction Steps

A mixture of 7-(azidomethyl)-4-phenylquinoline-2-carbonitrile (100 mg, 0.35 mmol), 3-ethylpent-1-yn-3-ol (47 mg, 0.42 mmol), copper iodide (100 mg, 0.52 mmol) and diisopropylethylamine (305 μL, 1.75 mmol) in THF (4 mL) was stirred at rt for 6 h. The reaction was quenched with saturated aqueous NH4Cl and extracted with EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure. Purification on silica gel (eluting with acetone/dichloromethane, 2:8) gave the title compound. MS (+ESI): 398 (M+H)+.
