The resulting mixture was stirred at room temperature for 2 hours. Water was added and the mixture was extracted with DCM. The combined extracts were washed with brine, dried over anhydrous Na2SO4, and concentrated to afford the title compound (1.4 g, 51%), which was used directly in the next step without further purification. MS (ESI): 270 [M+H]+.
