  • Raziskava mehanizma pretvorbe tritil-amlodipina v amlodipin benzensulfonat
    Furlan, Borut, 1959- ...
    The purpose of the investigation was to determine the reaction mechanism of the conversion of trityl-amlodipine into amlodipine benzensulfonate with benzenesulfonic acid and methanol. Therefore ... reaction rate measurements were performed in methanol, 2-propanol and in the mixture of both. Since the reaction with methanol occurs much faster than with 2-propanol it was concluded that it follows one-step SNZ mechanism without the formation of the free base in the transition state. On the basis of NMR measurements in deuterated methanol we found out that besides amino or protected amino group dihydropyridine ring is also protonated during the reaction course.
