The reaction mixture was allowed to slowly come to room temperature. Once the reaction was done by TLC, the reaction was acidified with acetic acid and then extracted with EtOAc (20 mL) and H2O (20 mL). The organic layer was dried over anhydrous Na2SO4(s), filtered, and concentrated to give the title compound (0.052 g, 71%).
