An efficient method for the transformation of benzyl alcohols
into their methyl or ethyl ethers has been established using 2,4,6-trichloro-1,3,5-triazine
(TCT) and dimethyl sulfoxide in methanol or ethanol. This procedure
chemoselectively converts benzylic hydroxys into their methyl or
ethyl ethers in the presence of aliphatic or phenolic hydroxys.
