Versuchsvorschrift
To a mixture of N-ethylcarbamate-5-hydroxy-6-chloro-8-methyl-1,2,3,3a,8,8a-hexahydroindeno[1,2-c]pyrrole, o-trifluoromethanesulfonate (60 mg, 0.14 mmol), palladium(II) acetate (6 mg, 0.028 mmol) and 1,3-bis(diphenylphosphino) propane (12 mg, 0.035 mmol) in MeOH (0.5 mL) and DMSO (0.5 mL) was added Et3N (0.2 mL, 1.4 mmol). The resulting mixture was stirred for 2 hours at 80° C. then cooled to room temperature. The reaction mixture was diluted with EtOAc (5 mL) and then washed with H2O (2 mL). The organic extract was dried over MgSO4 and concentrated to afford 15 mg (35% yield) of the subtitle compound, which was used without further purification. MS calculated for C15H18ClNO2+H: 280, observed: 280.
