Lysergic acid tert-butylamide

Lysergic acid tert-butylamide (LAtB), also known as N-tert-butyllysergamide (NtB-LA), is a psychedelic drug of the lysergamide family related to lysergic acid diethylamide (LSD). It was described in an early patent as reportedly being psychoactive and hallucinogenic and as producing hypothermia and "anti-hypothalamic" effects presumably in animals.
