Hydrazine hydrate (1:1) → (1-(Aminomethyl)hexahydrocyclopenta[c]pyrrol-2(1H)-yl)(5-methyl-2-(2H-1,2,3-triazol-2-yl)phenyl)methanone

Participants

Reaction Steps

A solution of 2-((2-(5-methyl-2-(2H-1,2,3-triazol-2-yl)benzoyl)octahydrocyclopenta[c]pyrrol-1-yl)methyl)isoindoline-1,3-dione (1 equiv.) and hydrazine monohydrate (4 equiv.) in MeOH (0.5M) was stirred at 70° C. for 3 h and then concentrated in vacuo to a yellow oil. The reaction mixture was diluted with EtOAc and washed with water, brine, dried (MgSO4), and concentrated. The crude residue was purified by chromatography on silica gel (20% MeOH in EtOAc) to firstly remove the impurities and then (2:8:1 MeOH/EtOAc/TEA) to elute the title compound which was concentrated to yield a yellow oil. MS (ESI) 326 (M+H).
