Reaction Steps

To a mixture of 6-aminoindan-1-one (7.2 g, 11.8 mmol) in conc. HCl (20 mL) at 0° C. was added dropwise an aqueous solution of NaNO2 (0.9 g, 13 mmol). After 30 min, a solution of SnCl2.2H2O (5.9 g, 26.2 mmol) in conc. HCl was added dropwise at such a rate that the reaction temperature never rose above 5° C. After the addition was completed, the mixture was stirred at RT for 2 h. The mixture was extracted with Et2O to afford 6-hydrazinoindan-1-one. MS (ESI) m/z: 199 (M+H+).
