Solid K2CO3 (547 mg, 3.96 mmol) was added, followed by the addition of 1-chloro-4-(chloromethyl)benzene (638 mg, 3.96 mmol). The reaction was permitted to stir at 60° C. for 36 h, at which time the reaction was allowed to cool to rt. Water was added and the resulting precipitate was isolated over a filter, and dried under high vacuum overnight to give 570 mg of the title compound.
