I know, the predicted M.P. seems a bit lower than one might expect. The experimental M.P. appears to be much more elusive though (SciFinder also cites predicted data). I'd try the relevant journal papers or maybe something like the Merck index, using the modification to your search term I suggested (also, the CAS number for this chemical is 64241-57-2). If you have synthesised this using a method in a manuscript, surely they gave product characterisation?
