3-Cyanophenol → 1,1-Dimethylethyl (2S)-4-({4-[({6-[(3-cyanophenyl)oxy]-3-pyridinyl}carbonyl)(methyl)amino]phenyl}methyl)-2-methyl-1-piperazinecarboxylate

Participants

Reaction Steps

The title compound was prepared from 1,1-dimethylethyl (2S)-4-({4-[[(6-chloro-3-pyridinyl)carbonyl](methyl)amino]phenyl}methyl)-2-methyl-1-piperazinecarboxylate (D54) and 3-cyanophenol in a similar manner to that described for D55 in Description 55 although the reaction temp./time was 130° C. for 24 h and purification was carried out by column chromatography. This gave the title compound as a colourless oil (0.184 g). MS (ES): MH+ 542.3.
