Seven milliliters of a THF solution of 14.2 g (55 mmols) of 1,4-dichloro-2-(trichloro)silyl-2-butene was cooled to -10° C., into which was gently dropped a mixed solution of 10 ml (55×3×1.5 mmols) of CH3OH and 34.5 ml (55×3×1.5 mmols) of (C2H5)3N. Subsequently, the mixture was agitated for 1 hour, to which was added 30 ml of dried ether. The resulting (C2H5)3N.HCl was removed by filtration and the solvent was distilled off under a reduced pressure and subjected to vacuum distillation to obtain 10.8 g of 1,4-dichloro-2-(trimethoxy) silyl-2-butene.
