The title compound, C(18)H(20)N(2)O(2), has been synthesized by the reaction of terephthaloyl chloride and 1,2,3,6-tetra-hydro-pyridine. This compound crystallizes as discrete mol-ecular species disposed about a crystallographic centre of symmetry, such that half the mol-ecule constitutes the asymmetric unit. The structure shows an envelope conformation for the dehydro-piperidine ring with the amide carbonyl twisted out of the benzene ring plane by 57.3 (2)°.

Cannabidiol (CBD), a specialized metabolite (phytocannabinoid) abundant in Cannabis sativa, is attracting increasing attention for its alleged health-promoting properties. The present study aimed to investigate the pharmacokinetics of CBD and its primary metabolite, 7-hydroxy-cannabidiol (7-OH-CBD), following a single oral dose of a CBD-rich Cannabis sativa extract, equivalent to 70 mg CBD, in healthy male (n=5) and female (n=6) participants. Using a randomized crossover design, the study evaluated the impact of a standardized high-fat meal compared to fasting on the oral bioavailability of CBD.
