Versuchsvorschrift

A solution of 1.6 ml (1.3 g, 0.040 mol) of methanol and 3.0 ml (2.2 g, 0.022 mol) of triethylamine in 100 ml of ether was stirred while a solution of 4.1 g (0.020 mol) of chloro(chloromethyl)methyl(phenyl)silane in 10 ml of ether was added dropwise. The resulting slurry was refluxed for 2 hours, cooled, washed with water, 0.1N aqueous HCl, saturated aqueous NaHCO3, water, and brine, dried over magnesium sulfate, and evaporated to leave 3.2 g of a pale yellow liquid. Distillation provided 1.7 g (42%) of the title compound as a colorless liquid: bp 46°-49° (0.05 mm); nD22 1.5207; nmr (CDCl3): 0.5 (3H, s), 3.0 (2H, s), 3.5 (3H, s) and 7.3-7.8 (5H, m).
