Reaction Steps

A solution of N-(6-hydroxy-pyridin-3-yl)-3,3-dimethyl-butyramide (0.42 g, 2.00 mmol), N-methyl-N-phenylcarbamoyl chloride (0.37 g, 2.20 mmol) and 1,4-diazabicyclo[2,2,2]octane (0.25 g, 2.20 mmol) in tetrahydrofuran (20 mL) was stirred at room temperature for 2.5 hours. Water was added and the solution was extracted three times with dichloromethane. The combined organic layers were dried over sodium sulphate, filtered and evaporated in vacuo. The residue was redissolved in ethyl acetate and the solution was filtered over a short pad of silicagel. Evaporation of the solvent and crystallisation of the solid from ethyl acetate:heptane yielded the title compound (0.54 g, 79% yield) as a white solid.
