1. The main framework is a five-membered ring consisting of:
   - Carbon-1 with a double-bonded oxygen;
   - Carbon-2 and carbon-3;
   - Carbon-4 with a double-bonded oxygen;
   - Nitrogen-5, closing back to Carbon-1.

2. The ring nitrogen (Nitrogen-5) carries a substituent consisting of a three-carbon chain whose terminal carbon (the third carbon away from Nitrogen-5) is both hydroxylated (-OH) and double-bonded to another nitrogen.

3. This second nitrogen is connected to a piperidine ring-a fully saturated six-membered ring containing one nitrogen and five carbons-at the para position relative to the piperidine's nitrogen. The piperidine's nitrogen is substituted by a phenyl ring bearing a single N,N-dimethylamino group (-N(CH3)2) at the para position on the benzene ring.
