User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a poly(ethylene glycol) derivative that is methoxypoly(ethylene glycol) in which the terminal hydroxy group has been converted to the corresponding 2-maleimidoethyl ether. Used particularly for the mPEGylation of free thiol groups in cysteine residues of proteins. It has a role as a reagent. It is a poly(ethylene glycol) derivative and a member of maleimides.
Assistant: This is a molecule that fits this description: COCCN1C(=O)C=CC1=O
