Versuchsvorschrift

To a stirred solution of 6-bromo-4-methyl-N-((1R,2S)-2-methylcyclohexyl)-1H-indole-2-carboxamide (4AH: 500 mg, 1.43 mmol) in xylene (7.5 mL) were added Pd(OAc)2 (58 mg, 0.26 mmol), JohnPhos (51 mg, 0.17 mmol), tBuOK (644 mg, 5.74 mmol) and aniline (802 mg, 8.62 mmol). The resulting mixture was purged with argon for 10 minutes and then heated at 100° C. for 3 h in sealed tube. The reaction mixture was partitioned between ethyl acetate and water. The organic layer separated and washed with brine and dried over Na2SO4, concentrated. The crude product was purified by column chromatography followed by preparative HPLC to obtain 160 mg of 4-methyl-N-((1R,2S)-2-methylcyclohexyl)-6-(phenylamino)-1H-indole-2-carboxamide (6A: 30%) as an off-white solid.
