The mixture was cooled to rt, water (100 ml) was added, and the slurry was stirred at rt for 30 min. The resulting solid was collected by filtration and air dried to afford 7-(azidomethyl)-4-chloroquinoline-2-carbonitrile (3-12, 4.75 g, 97%) as a white solid. LRMS m/z (M+H)+ 244.1 found, 244.65 required.
