Abstract: The difficulty of methylating a hindered piperidinyl, piperazinyl, or diazepinyl group with an Eschweiler-Clarke ("E-C") procedure without using a large molar excess (more than double) of formaldehyde is surprisingly found to be non-existent in the case of a diazacycloalkan-2-one group with a hindered N.sup.4 - or N.sup.5 -atom of its NH group which is to be methylated. The N.sup.4 - or N.sup.5 -atom of a polysubstituted diazacycloalkan-2-one group ("DCA") is substantially stoichiometrically converted even when a conventional E-C procedure is starved of HCHO, that is, with a much smaller molar excess of formaldehyde than deemed necessary. The effective molar ratio of NH groups: HCHO in the starved E-C process is in the range from 1:1 to 1:1.5, in the presence of enough formic acid to function both as reactant and solvent not only for a DCA-containing complex amine ("starting amine") to be methylated, but also for the methylated amine (product).

Abstract: An improved imaging technique involving nuclear magnetic resonance. Known drug or neurotransmitter receptor ligands are covalently bound to magnetic resonance image enhancing spin label compounds, such as sterically hindered free radical nitroxide compounds, with the resulting adduct being administered to a patient, and thereafter when the ligand is bound to specific receptor sites in the soft tissue such as the brain, regional tissue area is assessed with nuclear magnetic resonance, allowing diagnostic discrimination.
