ethyl (3aS,6aS)-2,3,3a,4,6,6a-hexahydro-1H-pyrrolo[2,3-c]pyrrole-5-carboxylate

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

Procedure: 0.255 of g 3-(3-fluorophenylsulfonyl)-8-iodoquinoline (0.617 mmol), 0.114 g of (3aS,6aS)-ethyl hexahydropyrrolo[3,4-b]pyrrole-5(1H)-carboxylate (0.617 mmol), 0.404 g of cesium carbonate (1.234 mmol), 0.014 g of palladium acetate (0.062 mmol) and 0.029 g of X-Phos (2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl, 0.062 mmol) in 5 mL toluene were stirred at 90° C. for 8 h. The reaction mixture was directly purified via silica gel chromatography (eluent toluene/methanol 10/1+2.5% triethylamine). Fractions containing the product were combined and the solvent was evaporated to yield 0.271 g of the desired product which was used in example 26 without additional purification. The reaction mixture was directly purified via silica gel chromatography (eluent toluene/methanol 10/1+2.5% triethylamine) Fractions containing the product the solvent was evaporated

Procedure: The titled compound was prepared in analogy to examples 2.2 and 2.3 using 2-chloro-5-(chloromethyl)pyridine 1-oxide (712 mg, 4 mmol), (3aS,6aS)-ethyl hexahydropyrrolo[3,4-b]pyrrole-5(1H)-carboxylate (1.1 g, 5.97 mmol), and K2CO3 (553 mg, 4 mmol). The obtained crude product was used without further purification in the next reaction step. The obtained crude product was used without further purification in the next reaction step
