User: I'm looking for the SMILES of a molecule that can be described by:
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.
Assistant: This is a molecule that fits your description: C[C@H](CN1CCOCC1)C(C(=O)N1CCCC1)(c1ccccc1)c1ccccc1
