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 (1.00 g, 1.914 mmol) and 4-chloro-2-(tributylstannyl)pyrimidine (0.966 g, 2.393 mmol) in DMF (5 mL) followed by Pd(PPh3)4 (0.111 g, 0.096 mmol, Strem) and Cut (0.072 g, 0.383 mmol, Aldrich). The reaction was stirred and heated in a Initiator microwave reactor at 100° C. for 1 h. The mixture was then diluted with DCM and washed with H2O, brine. The organic layer was dried (MgSO4), filtered and concentrated. The residue was purified with flash chromatography (eluent: 25%-60% EtOAc in Hexanes) to give 5-(3-(4-chloropyrimidin-2-yl)-1-tosyl-1H-indol-5-yl)-N-isopropyl-1,3,4-oxadiazol-2-amine (550 mg, 1.081 mmol, 56.4%) as a green solid. MS (ESI, pos. ion) m/z: 508.9 (M+1).
