The molecule consists of two rings joined by an ester linker (-O-C(=O)-).

The first ring is an oxolane:
  - It is a fully saturated five-membered ring, numbered with the hetero-oxygen as O1, followed clockwise by C2-C3-C4-C5.
  - C2 and C5 each bear two methyl groups on the same carbon (gem-dimethyl substitution).
  - C3 is the attachment point to the ester linker's oxygen atom.

Second ring is a benzene:
  - A benzene ring connected through its C1 to the ester carbonyl carbon.
  - On the benzene ring:
    - C2 bears a methyl group (-CH3).
    - C6 bears an amino group (-NH2).
