## Abstract The reactions of secondary alicyclic amines with the title substrate (PDTC) are subjected to a kinetic study in 44 wt.% aqueous ethanol, 25.0Β°C, ionic strength 0.2 M (KCl). Pseudo‐first‐order rate coefficients (__k__~obs~) are found under amine excess. Linear plots of [__N__]/__k__~obs~
