The resulting mixture was stirred for 16 hours, and then dichloromethane (DCM) was added. The mixture was successively washed with water and brine, dried and concentrated to give a residue that was purified by column chromatography to afford 12.3 g of the desired compound as a solid. LC-MS: m/z 267 (M+H+).
