To a solution of 6-bromo-4-{5-[(8aS)-hexahydropyrrolo[1,2-a]pyrazin-2(1H)-ylmethyl]-1,3,4-oxadiazol-2-yl}-1-(phenylsulfonyl)-1H-indazole (100 mg, 0.184 mmol) was added N-[2-(methyloxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methanesulfonamide (72.5 mg, 0.221 mmol), 1,1′-bis(diphenylphosphino)ferrocene palladium dichloride (36 mg, 0.049 mmol) and potassium phosphate tribasic (126 mg, 0.594 mmol). The mixture was heated under microwave irradiation at 100° C. for 20 mins. The mixture was passed through a 1 g silica SPE cartridge, washing with MeOH. The solvent was removed under a stream of nitrogen and the residue was partitioned between DCM (10 ml) and water (10 ml), separated with a hydrophobic frit and the solvent again removed under a stream of nitrogen. The residue was dissolved in DCM and added to the top of a 10 g silica SPE cartridge that was subsequently eluted with 0-15% MeOH/DCM over 20 mins. The product-containing fractions were combined and the solvent removed in vacuo to give the title compound as an orange oil (95 mg).
