The reaction was quenched by addition of ethyl acetate (1 mL) and H2O (3 drops), and the mixture was stirred for 30 min. The mixture was dried over Na2SO4, filtered through celite, and the filtrate was concentrated under reduced pressure. The residue was purified by MPLC (MeOH:CH2Cl2=1:50 (v/v) to 1:20 (v/v)) to afford the title compound (16.9 mg, 23%).
