Potassium Hydroxide → HCID 22722136, compound

Potassium hydroxide (2.57 g) was dissolved in dimethyl sulfoxide (8.0 mL). (4-Chlorophenyl)acetonitrile (1.58 g, 10.4 mmol) and 1,3-dichloro-2-(methoxymethoxy)propane (1.993 g) were dissolved in ethyl ether (3 mL), and this mixture was added dropwise to the vigorously stirred potassium hydroxide solution at room temperature. After stirring at room temperature for one hour, the reaction was quenched by adding ice-cold water (5.5 mL). The mixture was filtered through a pad of celite which was washed with ether (30 mL). The filtrate was added to a separatory funnel, and the aqueous layer was extracted with ether (3×15 mL). The organic layers were combined, dried over magnesium sulfate, filtered, and concentrated. The product was purified by silica gel chromatography to provide 1-(4-chlorophenyl)-3-(methoxymethoxy)cyclobutanecarbonitrile (1.28 g) as a mixture of isomers (ca. 2:1).
