Reaction Steps

Charge a 4 mL reaction vial with 4-(4-(4-(methylamino)piperidine -1-yl)phthalazin -1-yl)benzonitrile dihydrochloride (44.7 mg, 0.107 mmol), dichloromethane (1 mL), and triethylamine (0.0598 mL, 0.429 mmol). Flush the reaction vial with nitrogen and add 4-fluoro-2-(trifluoromethyl)benzoyl chloride (033 g. 0.14 mmol). Cap the vial and allow the reaction to stir at room temperature overnight. Evaporate to a residue and purify using silica gel chromatography (40:60, ethyl acetate:hexane, then ethyl acetate). Add 1 N HCl in diethyl ether to a solution of the isolated product in dichloromethane/methanol and remove the solvents by placing under a stream of nitrogen gas. Dry in a vacuum oven at 50° C. to obtain the title compound (36.0 mg. 59%). ES/MS m/z 533.8 (M+1).
