The reaction was cooled to 25° C., quenched with water (10 ml), and extracted with MTBE (4×30 ml). The combined organic fractions were then dried, filtered, and concentrated. The resulting solid was purified by column chromatography (DCM-MeOH=50:1) to give the title compound (0.035 g, 12%). MS: Calcd.: 303. Found: [M+H]+ 303.
