Procedure

Tert-butyl [1-(4-chlorobenzyl)-7-cyano-1,2,3,4-tetrahydronaphthalen-2-yl]carbamate (52 mg, 0.131 mmol, cf. example 30d) were dissolved in methanol (5 mL). Raney nickel (about 30 mg) was added and the reaction mixture was stirred at room temperature for 4 h under an atmosphere of hydrogen. The catalyst was removed by filtration. The solvent was evaporated in vacuo. The crude product was used without further purification for the next step. Yield: 32 mg (0.087 mmol, 67%).
