Trifluoroacetic acid → 5-Benzyl-octahydropyrrolo(3,4-c)pyrrole-1,3-dione

Participants

Reaction Steps

To a suspension of TFA (1.02 g) and 1H-Pyrrole-2,5-dione (10.22 g) in CH2Cl2 (250 mL) at −5° C. was added a solution of N-(methoxymethyl)-N-(trimethylsilylmethyl)benzylamine (29.99 g) in CH2Cl2 (20 mL) dropwise over 1 h. The reaction mixture was stirred at room temperature for another 5 h and evaporated in vacuo. The residue was stirred in the mixed solvent (EA: PE=3:7) at −10° C. for 1 h, and the mixture was filtered to afford the title compound as a white solid (10.18 g, 42.00%).
