3,5-bis-(1,1-dimethylethyl)-4-hydroxy-N-[(4-nitrophenyl)methyl]-benzamide → 4-acetoxy-3,5-dimethoxy-N-[2-(4-aminophenyl)ethyl]-benzamide

Participants

Reaction Steps

The experimental protocol used is the same as that described for intermediate 2-2, with 4-acetoxy-3,5-dimethoxy-N-[2-(4-nitrophenyl)ethyl]-benzamide replacing the 3,5-bis-(1,1-dimethylethyl)-4-hydroxy-N-[(4-nitrophenyl)methyl]-benzamide. A colourless oil is obtained with a quantitative yield. The product is used directly in the following stage without additional purification.
