Reaction Steps

(R)-1-(2-methylpiperazin-1-yl)-4-phenylphthalazine (JK-10) (509 mg, 1.67 mmol), 4-oxocyclohexanecarboxylic acid (261 mg, 1.84 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (273 mg, 2.01 mmol) (HOAt), N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (385 mg, 2.01 mmol), sodium bicarbonate (281 mg, 3.34 mmol), and DMF (6 mL) were stirred at rt for 22 hours. The reaction was taken up in ethyl acetate (80 mL) and washed with aqueous K2CO3 (10%), water, and saturated sodium chloride. The organics were dried (MgSO4) and evaporated to give a yellow oil. Chromatography over silica gel with a gradient of hexanes/0-70% ethyl acetate gave an off-white solid, compound 69. MS (M+H)+=429.2.
