The novel linker methyl 2-(4-methoxycarbonylbutyldimethylsily)ethanol (3) was synthesized in 58% overall yield over four steps, starting from 2-(hexenyldimethylsilyl)ethanol. Galactopyranosylation of 3 and coupling of the resulting linker galactoside to aminomethylated polystyrene resin gave a material that could be efficiently de-O-benzoylated as well as O-propionylated. Treatment of the resin with
