Reaction Steps

To a stirred suspension of sodium hydride (0.25 g of a 60% dispersion in mineral oil, 5.1 mmol) in N,N-dimethylacetamide is added dropwise a solution of 4′-chloro-3-hydroxy-2,2,4-trimethylvaleranilide (1.5 g, 5.6 mmol) in N,N-dimethylacetamide. After stirring for 40 minutes at room temperature, iodomethane (1.58 g, 11.1 mmol) is added. The reaction mixture is stirred at room temperature for 18 hours, diluted with water, and extracted with ether. The combined organic extracts are washed with brine, dried over anhydrous magnesium sulfate, and concentrated in vacuo to obtain a semisolid. Flash column chromatography of the semi-solid using silica gel and an ethyl acetate/hexanes solution (1:10) gives the title product as a white solid (0.71 g, mp 103-107° C.) which is identified by 1H NMR spectral analysis.
