Under nitrogen, a 500 ml Schlenk flask was cooled to room temperature, charged with 150 ml of diethyl ether and cyclopentylmagnesium chloride (0.055 mol, 27.7 ml) and warmed slightly to 30° C. A 100 ml Schlenk flask was purged with nitrogen and charged with 75 ml hexane and 3,3,3-trifluoropropyltrimethoxy silane (10 ml, 0.0504 mol). The silane/hexane solution was added dropwise via cannula to the Grignard/diethyl ether mixture producing a white cloudy mixture. After addition (1.25 hrs.), the Grignard containing flask was rinsed once with 25 ml of hexane. The reaction mixture was stirred at room temperature for one hour.
