Looking for a protocol

A method using benzyl chloride was publishes a couple of years back in NAR.
I do not have the ref. handy, but a search w/ those two terms should be
sufficient. It works quite nicely for small amounts of tissue and yields
digestible and amplifiable DNA. However, it is a nasty compound and has to
be fresh to obtain good quality DNA. I suspect that old (>3mo) benzyl
chloride modifies certain bases. It is itself oxidized upon storage (hence
the need to store under inert gas). Unfortunately, it is hard to obtain the
compound in small amounts in the US. Ideally, buying about 25 to 50mL at a
time would be really great.
