After 5 h. The mixture was cooled to rt and the solvent was removed in vacuo. The residue was diluted with brine and extracted with EtOAc. The combined organic layers were washed with brine, dried over anhydrous MgSO4, and concentrated in vacuo to give the nitrile (171 mg, 94%) as a solid. MS(ESI+) m/z 506 (M+H)+.
