実験手順
Compound 549 (1.06 g, 3.68 mmol) and 1-methylpiperazine (0.818 mL, 7.37 mmol) were dissolved in toluene (40 mL) and stirred at 110° C. for 16 h. The toluene was removed on the rotary evaporator. The crude product was dissolved in ethyl acetate and washed with water. The organic layer was separated and dried with Na2SO4, filtered and concentrated via rotary evaporation. The residue was purified via Isco employing a 0 to 50% methanol:ethyl acetate solvent gradient to afford compound 550 (0.86 g, 66%) as a white solid.
