실험 절차

To a solution of but-3-en-2-ol (5.0 g, 69.34 mmol) in CH2Cl2 (100 mL) at 0° C. was added imidazole (5.66 g, 1.2 eq) and TBSCl (10.45 g, 1.0 eq). The reaction mixture was stirred at 0° C. to rt for 3 h. Solid was filtered off, the filtrate was concentrated and passed through a short silica gel column by eluting with hexane to give tert-butyl-dimethyl-(1-methyl-allyloxy)-silane (10.86 g, 85%) as a colorless oil.
