Patent ID: 7915439

Claim:
A method of manufacturing a silylalkoxymethyl halide of formula (1): wherein R 1 , R 2 , and R 3 are an alkyl, cycloalkyl, aryl group, or a halogen atom, R 4 is a divalent hydrocarbyl group having 1 to 10 carbon atoms, and X is a halogen atom, comprising reacting: (a) a silyl alcohol compound of formula (2): wherein R 1 , R 2 , and R 3 are an alkyl, cycloalkyl, aryl group, or a halogen atom, and R 4 is a divalent hydrocarbyl group having 1 to 10 carbon atoms, with (b) formaldehyde or a polymer thereof, and (c) a halosilane; and distilling out, under reduced pressure, hydrogen halide generated as a by-product in the reaction, excess halosilane, and the reaction product of water and halosilane and thereafter adding (d) a tertiary amine.
