実験手順
The title compound was prepared from 1,1-dimethylethyl (2R)-2-methyl-4-[(4-nitrophenyl)methyl]-1-piperazinecarboxylate (D24) using a method similar to that described for D22 in Description 22 although aqueous 2M KOH solution was used in place of solid KOH and the reaction time was 0.5 h. MS (ES): MH+ 306.2, MNa+ 328.2.
