Task: Please create a text description for a molecule based on its representation.
SMILES: C[C@H](CN1CCOCC1)C(C(=O)N1CCCC1)(c1ccccc1)c1ccccc1
Constraint: Answer the question with full sentences.
Result: The molecule is an N-acylpyrrolidine arising by formal condensation of pyrrolidine with (3S)-3-methyl-4-(morpholin-4-yl)-2,2-diphenylbutanoic acid. An opioid analgesic that is structurally related to methadone, it is more poweful than morphine but shorter acting. It has been used (particularly as the hydrogen tartrate salt) for the treatment of severe pain, but was discontinued in the UK in 2004. It has a role as an opioid analgesic. It is a member of morpholines and a N-acylpyrrolidine.
