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 Cc1[nH]c(C=C2C(=O)Nc3ccc(F)cc32)c(C)c1C(=O)O.NCCNc1ccc(C(=O)Nc2ccc(C(F)(F)F)cc2N)cn1 .
