Water → Ethyl 3-(6-aminopyridin-3-yl)-2-(1-but-2-ynyl-1H-imidazol-4-yl)propionate

Participants

Reaction Steps

11 mg (0.23 mmol, 50%) of sodium hydride were added to a solution of 60 mg (0.23 mmol) of ethyl 3-(6-aminopyridin-3-yl)-2-(1H-imidazol-4-yl)propionate (example 1g) in 0.5 ml of DMF at RT and stirred for 1 h. Then 31 mg (37 μl, 0.23 mmol) of 1-bromo-2-butine were added, and the mixture was stirred at RT for 1 h. 1 ml of water was then added and the mixture was extracted with EA. The organic phase was dried over Na2SO4, filtered and concentrated. Chromatography of the residue on silica gel afforded 28 mg of the title compound.
