10.0 g (36.4 mmol) of chloro-tert-butyl(diphenyl)silane dissolved in 88 ml of tetrahydrofuran were added dropwise over a period of 6 h to a solution of 10.1 ml (182 mmol) of 1,2-ethanediol and 2.97 g (43.7 mmol) of imidazole in 12 ml of tetrahydrofuran, and the mixture was then stirred further at RT overnight. The solvent was removed under reduced pressure and the residue was purified by flash chromatography (340 g silica cartridge, 100 ml/min, cyclohexane/ethyl acetate gradient). Yield: 8.34 g (76% of theory)
