Reaction Steps

A stirred mixture of 6-bromo-2-tetralone (17.6 g, 78.2 mmol), sodium cyanide (9.58 g, 195 mmol), and ammonium carbonate (97.7 g, 1.02 mol) in H2O (100 mL) and EtOH (100 mL) was heated to 70° C. for 3 h, then allowed to cool to ambient temperature. The precipitate was collected by filtration and washed with H2O (5×200 mL). Drying in vacuo afforded the title compound as a pale solid. MS: m/z=297 (M+1).
