Versuchsvorschrift

1,1-Bis(hydroxymethyl)cyclopropane (1.0 g, 0.0098 mol), triethylamine (TEA) (2.0 mL, 0.015 mol), and 1H-imidazole (0.13 g, 0.0020 mol) were dissolved in anhydrous DCM (15 mL) and the solution was cooled to 0° C. A solution of tert-butyldimethylsilyl chloride (1.55 g, 0.0103 mol) in DCM (5 mL) was added drop-wise and the resulting mixture was allowed to warm to RT and stirred overnight. The reaction was quenched with saturated aqueous NaHCO3 and extracted with DCM (3×). The organic extract was dried (magnesium sulfate), filtered, and concentrated in vacuo. The crude product was identified by 1H NMR and used in the next step without further purification.
