Benzyl cyanide (10.05 ml, 87.07 mmol, 100 mol-%) was dissolved in EtOAc (200ml) in around-bottom flask. Metallic natrium (2.8 g, 121.795 mmol, 140 mol-%), stored in oil, wascut, washed in isopropanol and added to the mixture. The mixture was heated to 80 °Cand held for 18 h under stirring. The mixture was allowed to cool to room temperature,
the solids were collected by filtration and dissolved in H2O. The solution was made acidicwith conc. HCl, extracted with EtOAc (2 x 20 ml), dried with MgSO4 and concentrated invacuum to give 6.339 g of a light yellow crude APAAN powder.
