Procedure

To a solution of N-[(2S)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-inden-2-yl]-2-propanesulfonamide (250 mg, 0.68 mmol) in dry 1,4 dioxane (5 ml), polymer supported Pd(PPh3)4 (70 mg, 0.11 mmol/g, 0.0068 mmol) was added along with 5-methyl-3-pyridinyl trifluoromethanesulfonate (241 mg, 1.026 mmol) and 680 μl of a 2M Na2CO3 solution in water and the resulting mixture was heated at 90° degrees for 3 hours. Then after cooling the resin was removed by filtration and then the solvent was removed under reduced pressure. The residue was taken up with DCM, washed with water and loaded on a 25M+ silica cartridge eluating with a cyclohexane/AcOEt 75/25 mixture. 95 mg of title compound were recovered as whitish solid (42%). Due to the use of chiral Intermediate 7, the final compound is believed to be N-[(2S)-5-(5-methyl-3-pyridinyl)-2,3-dihydro-1H-inden-2-yl]-2-propanesulfonamide.
