실험 절차

In a 500 ml three-neck flask provided with a magnetic stirrer and a reflux condenser were charged 29.3 g (0.129 mole) of cyclopentyl triethoxysilane, 165.9 g (2.24 mole) of tert-butyl alcohol and 2.06 g (30.3 m mole) of sodium ethoxide, which were then reacted with each other in an oil bath of 85° C. for 24 hours under stirring. Then, trimethylchlorosilane was added to neutralize the alkali. Then, 21.6 g (0.0828 mole) of tert-butoxy cyclopentyl diethoxysilane were obtained by vacuum distillation. Its structure was confirmed as in Example 1. The yield was 64%.
