Maybe i could tap it off with the sep funnel & try to crash it out e.g. with MeOH.

Alternatively, i heard of a method called salting out that some people use.

I seem to recall that p-substituted methoxybenzaldehyde are usually troublesome. Have you checked out Vol 3 of the Organic Reactions series? Its available in the SM library, page 269 onwards.
