Triethylamine → Methyl-phenyl-carbamic Acid pyrimidin-2-yl Ester

Participants

Reaction Steps

A solution of 2-hydroxypyrimidine hydrochloride (0.40 g, 3.00 mmol), 1-methyl-3-(methyl-phenyl-carbamoyl)-3H-imidazol-1-ium iodide (1.03 g, 3.00 mmol) and triethylamine (0.83 ml, 6.00 mmol) in acetonitrile (15 ml) was stirred at room temperature overnight. The solvent was evaporated in vacuo and the residue was purified by flash column chromatography (SiO2, ethyl acetate) followed by crystallisation from ethyl acetate:heptane yielding the title compound (0.08 g, 12% yield) as a white solid.
