Procedure
Lit. Tetrahedron 2004, 60, 7397-7403. To a stirred suspension of 1.34 mmol 5-bromo-1,3-dihydro-isoindole-2-carboxylic acid tert-butyl ester (CAS: 201940-08-1) in 2 ml dioxane were added 0.03 mmol 1,1′-bis(diisopropylphosphino)ferrocene, 0.03 mmol palladium acetate, 1.61 mmol sodium tert-butoxide and 2.68 mmol ethanethiol and the mixture was stirred at 100° C. for 16 h. The reaction mixture was then cooled to room temperature, diluted with ethyl acetate/tetrahydrofuran and washed with brine. The organic phase was dried over sodium sulfate and concentrated in vacuo to yield the title compound as a brown oil which was used in the next step without further purification.
