Imidazole (389 mg, 5.72 mmol) was added to a suspension of 2-[(2-chloropyrimidin-4-yl)oxy]ethanol (416 mg, 2.38 mmol) in dichloromethane (9.5 mL) at 0° C. tert-Butyldimethylsilyl chloride (424 mg, 2.81 mmol) was added and the reaction mixture stirred at room temperature for 2 h. The reaction was quenched with water and the organic layer separated. The organic layer was dried over sodium sulfate, filtered, and concentrated to give 4-(2-{[tert-butyl(dimethyl)silyl]oxy}ethoxy)-2-chloropyrimidine (678 mg, 2.35 mmol, 99% yield) as a clear, yellow oil. MS ESI: [M+H]+ m/z 289.1.
