Procedure

A suspension of 1-[2-(2-methoxy-ethoxy)-1,1-dimethyl-ethyl]-4-nitro-benzene (8.1 g, 32 mmol) and Raney Ni (1 g) in MeOH (50 mL) was stirred under H2 (1 atm) at room temperature for 1 h. The catalyst was filtered off and the filtrate was concentrated to obtain 4-[2-(2-methoxy-ethoxy)-1,1-dimethyl-ethyl]-phenylamine (5.5 g, 77%).
