You are a chemist. Now you are given a product molecule. Please predict the the reactant molecules of the reaction.
The reaction equation has the following format:
```
reactant1.reactant2. ... .reactantN>>product
```
Your task is to predict the structure representation of the reactant molecule. We provide the SMILES of the reactants.
system
Do retrosynthesis with the product <molecule_2d> .

OK. The reactants may be CNC(=O)c1c(-c2ccc(Cl)cc2)oc2cc(N(c3ccc(O)c(F)c3)S(C)(=O)=O)c(C3CC3)cc12.O=S(=O)(OS(=O)(=O)C(F)(F)F)C(F)(F)F .
