実験手順

To a suspension of sodium hydride (60% dispersion in mineral oil, 0.80 g, 20.0 mmol) in 15 mL dry dimethylformamide under argon, cooled in an ice-bath was added dropwise a solution of 2-imidazolidone (1.72 g, 20.0 mmol) in 5 mL dimethylformamide. The ice bath was removed, the mixture was stirred 30 minutes and a solution of 5'-chloromethyl-2'-hydroxyacetophenone (1.85 g, 10.0 mmol) in 5 mL dimethylformamide was added dropwise. The mixture was stirred four hours and the product was isolated in the same manner as in the previous example to give a solid. The solid was stirred under 20 mL n-butylchloride, filtered off, and dried in vacuo to give 1.01 g (43%) product as a white solid, mp 131°-133° C.
