The piperidine material, pip-T, is made via the glyoxylamide (mp 182-183 ¡ÆC) which is reduced with LAH to the target amine (mp 149-150 ¡ÆC, HCl salt 220-221 ¡ÆC). The morpholine analogue also came to be via the glyoxylamide (mp 187-188 ¡ÆC) and the reduction to the amine which can be an oil, but which has been reported to have a mp 145-147 ¡ÆC. The only trials I know of with either of these is with mor-T which, as the fumarate salt, had no effects at all upon the i.m. injection of a 30 milligram bolus.
Perhaps, as a favor to the good doctor if nothing else, your friend should consider producing and bioassaying the aforementioned material, and reporting his/her findings ;)
