Potassium Phosphate, Tribasic → 5-(4-{2-[3-(5,6-Dihydro-7H-imidazo[2,1-c][1,2,4]triazol-7-yl)phenyl]ethyl}-1-piperazinyl)-2-methylquinoline

Participants

Reaction Steps

5-{4-[2-(3-Iodophenyl)ethyl]-1-piperazinyl}-2-methylquinoline (59 mg), 5,6-dihydro-1H-imidazo[2,1-c][1,2,4]triazole (50 mg, 3.5 equiv.), palladium(II) acetate (9 mg, 0.3 equiv.) 2-(dicyclohexylphosphino)-2′-methylbiphenyl (42 mg, 0.9 equiv.) and potassium phosphate (97 mg, 3.5 equiv.) were suspended in DME and stirred at 150 C under microwave irradiation for 2 h. The mixture was cooled to room temperature, diluted with methanol and loaded onto an ion-exchange cartridge (SCX-2), which was eluted with methanol followed by ammonia-methanol solution (1M). The combined basic fractions were concentrated under vacuum and purified using column chromatography [SiO2; DCM-MeOH (90:10)] to afford the title compound as colourless solid (13 mg, 26% yield).
