Reaction Steps

0.130 g (1.29 mmol) of triethylamine and 0.155 g (1.29 mmol) of pivaloyl chloride were added to 0.263 g (1.42 mmol) of 2-(2,5-dimethylcyclopenta-1,4-dienyl)phenylamine solution melted in 10 mL of MC solvent, and then reacted at room temperature for 1 hour. 5 mL of 2N HCl was added to the reaction product and strongly stirred for a few minutes. The organic layer was neutralized using 5 mL of NaHCO3, and the product was filtered using a column chromatography with a hexane/ethyl acetate (v/v, 10:1) solvent. The refined product was dried in vacuum to remove the solvent therein, thereby obtaining while solid (0.355 g, 93%).
