2-Methyl-2-(4-nitrophenyl)propanenitrile → 2-(4-Aminophenyl)-2-methylpropanenitrile

Participants

Reaction Steps

16 g (84.1 mmol) of 2-methyl-2-(4-nitro-phenyl)-propionitrile (Example 1d) and 4.16 g of Raney-Ni are shacked in 160 ml of THF-MeOH (1:1) under 1.1 bar of H2 for 12 h. at RT. After completion of the reaction, the catalyst is filtered-off and the filtrate is evaporated to dryness. The residue is purified by flash chromatography on silica gel (hexane-EtOAc 3:1 to 1:2) to provide the title compound as an oil. ES-MS: 161 (M+H)+; analytical HPLC: tret=2.13 minutes (Grad 1).
