N-Acetyl-D-alpha-asparagyl-N1-{(2S)-4-[{(1R)-1-[1-benzyl-4-(2,5-difluorophenyl)-1H-pyrrol-2-yl]-2,2-dimethylpropyl}(glycoloyl)amino]-1-[(2-[(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetyl]amino}ethyl)amino]-1-oxobutan-2-yl}-L-aspartamide The synthesis of the title compound commenced with the reaction of 1-acetoxypyrrolidine-2,5-dione in DMF with (2R)-2-amino-4-tert-butoxy-4-oxobutanoic acid in the presence of N,N-diisopropylethylamine. The intermediate obtained was then reacted in DMF with Intermediate C116 by means of HATU coupling in the presence of N,N-diisopropylethylamine. In the last step, the tert-butyl ester was detached by stirring at 50° C. with 6 equivalents of zinc chloride in trifluoroethanol for 40 min. LC-MS (Method 1): Rt=0.92 min; MS (ESIpos): m/z=964 (M+H)+. |
