The resulting mixture was stirred at room temperature for 18 h. The reaction was quenched with H2O (2 drops), purified with a Gilson HPLC (with 0.1% TFA), concentrated, re-dissolved in EtOAc, washed with NaOH (1N), dried over Na2SO4, filtered, concentrated and dried with a high vacuum oil pump to afford the title compound as a white solid 38.5 mg (53%). LC-MS m/z 729 (M+H)+.
