Dear members,

Sometimes you need to protect an OH group of alcohol and phenol.
Methoxymethyl chloride is often used in such cases.

However, there is other alternative to use. It is methoxymethyl acetate. It protects alcohols and phenols under very mild conditions. Your yield might be much better, too.

Some years ago I published a paper:

"On reactivity of methoxymethyl acetate towards alcohols and
phenols", J. Krol, G. Grynkiewicz, A. Kutner, Polish J. Chem.,
65, 1433, (1991).

See my web page:

Yours sincerely,
