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
<molecule_2d> Given the product provided, propose some possible reactants that could have been employed in its formation.
user
Here are possible reactants: COC(=O)C(Cc1ccc(N)cc1)NC(=S)C1(CCCCS(C)(=O)=O)CCCC1.O=C(Cl)c1c(Cl)cccc1Cl .
