25021-08-3, The molecularity of an elementary reaction is the number of molecules that collide during that step in the mechanism. If there is only a single reactant molecule in an elementary reaction, that step is designated as unimolecular.25021-08-3, name is 2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid. A new synthetic method of this compound is introduced below.

Trifluoroacetic acid/(2S)-2-amino-4-[{(1R)-1-[1-benzyl-4-(2,5-difluorophenyl)-1H-pyrrol-2-yl]-2,2-dimethylpropyl}(glycoloyl)amino]-N-{2-[(2-{[(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetyl]amino}ethyl)sulphonyl]ethyl}butanamide (1:1) The title compound was prepared from Intermediate L81 by coupling with Intermediate C58 in the presence of HATU and N,N-diisopropylethylamine. In the next step, the Z protective group was removed by hydrogenation over 10% palladium on activated carbon in DCM/methanol 1:1 at RT under hydrogen standard pressure for 30 min. The deprotected intermediate was then converted by coupling with (2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid in the presence of HATU and N,N-diisopropylethylamine and finally by deprotection with zinc chloride into the title compound. LC-MS (Method 1): Rt=0.83 min; MS (ESIpos): m/z=785 (M+H)+.
