実験手順
A glass microwave reaction vessel was charged with 5-(3-iodo-1-tosyl-1H-indol-5-yl)-N-isopropyl-1,3,4-oxadiazol-2-amine (800 mg, 1.532 mmol) and 4-((4-methoxybenzyl)oxy)-2-(methylsulfonyl)-6-(trimethylstannyl)pyrimidine (875 mg, 1.914 mmol) in DMF (5 mL) followed by Pd(PPh3)4 (88 mg, 0.077 mmol) and CuI (72.9 mg, 0.383 mmol). The reaction mixture was stirred and heated in an Initiator microwave reactor (Personal Chemistry, Biotage AB, Inc., Upssala, Sweden) at 100° C. for 1 h. The mixture was filtered through a plug of celite and washed with DCM. The filtrate was washed with water (25 mL×3) and the organic layer was dried, filtered and concentrated. The residue was purified with silica gel chromatography (eluting with 10-20% EtOAc in DCM with 1% MeOH) to give N-isopropyl-5-(3-(6-((4-methoxybenzyl)oxy)-2-(methylsulfonyl)pyrimidin-4-yl)-1-tosyl-1H-indol-5-yl)-1,3,4-oxadiazol-2-amine (660 mg, 0.958 mmol, 62.6% yield) as a brown solid. MS (ESI, pos. ion) m/z: 688.8 (M+1).
