This molecule is an amide linking a furan ring to a piperidine ring. The amide is formed by a connecting carbonyl group and the nitrogen on the piperidine ring. The furan ring is five-membered, containing one oxygen and four carbons, and is attached to the carbonyl through the carbon adjacent to the ring oxygen (i.e., its 2 position). The carbonyl's other bond connects to the nitrogen of a six membered piperidine ring. Within this piperidine ring (numbered so that the nitrogen is N-1), there is a single methyl group on C-3 and two methyl groups on C-5 (gem dimethyl).
