The reaction mixture was cooled to room temperature, filtered and the filtrate was evaporated and extracted with dichloromethane (3×). The combined organic solutions were washed with water and brine, dried (MgSO4), filtered and concentrated under reduced pressure to give the title compound as a white solid, 15.5 g.
