Amine (1 mmol, as liquid or fine powder) and the
above mixture were mixed thoroughly and then subjected
to the 80% power radiation of our domestic microwave
oven for a certain period of time. The progress of each reac-
tion was monitored by TLC using n-hexane/acetone (3:1)
as the solvent. After completion of the reaction the ob-
tained mixture was allowed to cool, eluted with ethanol, fil-
tered and followed either by crystallization or successive
solvent evaporation and vacuum distillation.
