I followed the procedure listed, using DMSO solvent, anisaldehyde, & NaCN, but on adding the water to the anisoin at 20 hrs of RT stirring, it did
not crystallize but remained in solution as an oil.

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.

According to this source, after 15 experiments, only in one case did it reach 35%.

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.
