1-benzyl-5-methyl-2,3,3a,4,6,6a-hexahydropyrrolo[2,3-c]pyrrole

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 10.3 g (47.6 mmol) of 2-benzyl-7-methyl-2,7 -diazabicyclo[3.3.0]octane in 200 ml of ethanol are hydrogenated at 100° C. and 100 bar on 2.5 g of palladium-active carbon (10% Pd). The catalyst is filtered off with suction, the filtrate is concentrated and the residue is distilled. are hydrogenated at 100° C. The catalyst is filtered off with suction the filtrate is concentrated the residue is distilled

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
