    • General procedure for the synthesis of MCR products 4a-h and 6a-h (GP-MCR): Fluoroaniline 1 (1 mmol) and aldehyde 2 (1 mmol) were stirred in 3 mL TFE for 2 h. Then, carboxylic acid (1 mmol) and isocyanide 3 (1 mmol) were added and the reaction mixture was stirred for 16 h at room temperature. The solvent was removed in vacuo. The MCR products were generally obtained in high yields and high purities (determined by HPLC-MS) and they were used in the next step without further purification.
