Preparation of tert-butyldimethoxysilane A 1 mol / l solution of dimethyldichlorosilane (1.15 equivalents) in pentane was cooled to 0 ° C and a tert-butyl file (1.0 equiv.) Was added dropwise under nitrogen in the presence of stirring. Pentane solution. After the temperature was kept at 0 ° C. and stirred for 1.5 hours, stirring was continued at 25 ° C. for 48 hours. Distillation, collecting the boiling point of 125 ° C / 733mm fractions, the yield was 70% pure. Let stand curing.
For drug intermediates and organic synthesis, is a hindered silicone protective agent, widely used in the synthesis of the original drug. In the synthesis of ribonucleosides for the hydroxyl protective group, but also the oxidant, decyanation agent.
