Procedure

Tert-butyl 1-benzyl-7-cyano-1,2,3,4-tetrahydronaphthalen-2-ylcarbamate (1.1 g, 3.03 mmol) was dissolved in dichloromethane (20 mL) and 5 M hydrochloric acid in isopropanol (2 mL) was added. The reaction mixture was stirred at room temperature for 12 h followed by 4 h at 35° C. The solvent was evaporated in vacuo. Water (30 mL) was added and the pH was adjusted to pH 9 using aqueous saturated sodium bicarbonate solution. The aqueous layer was extracted with dichloromethane. The combined extracts were dried (MgSO4) and the solvent was evaporated in vacuo. Yield: 790 mg (3.03 mmol, 100%).
