Participants

Reaction Steps

4-nitro-N-(tert-octyl)benzamide (30 g, 0.108 mol) dissolved in 200 ml of ethyl acetate was hydrogenated in a 500 ml hydrogenator in the presence of 4.8 g of palladium, 10% on charcoal with 50% water as the catalyst (hydrogen pressure: 8-10 bar) at a temperature of 70-75° C. for 1 hour and 15 minutes. After filtering, concentrating the solvent and vacuum drying, 20.4 g (yield: 76%) of 4-amino-N-(tert-octyl)benzamide were obtained in the form of a pale yellow powder and used as is in the next step.
