Versuchsvorschrift

Dissolve N-methyl-1-(4-(1-methyl-1H-pyrazol-5-yl)phthalazin-1-yl)piperidin-4-amine (100 mg, 0.31 mmol), 4-chloro-2-(methylsulfonyl)benzoic acid (87 mg, 0.37 mmol) and diisopropylethylamine (0.26 mL, 1.5 mmol) in DMF:DMSO=4:1 (2 mL) at 60° C. Cool to 0° C. and add pentafluorophenyl diphenylphosphinate (250 mg, 0.65 mmol) in DMF:DMSO=1:1 (1 mL) to the solution. Stir the mixture at 60° C. overnight. Cool the reaction mixture to ambient temperature and dilute with CH2Cl2, wash with brine, dry over Na2SO4, and concentrate under reduced pressure. Purify the resulting residue by flash silica gel chromatography (hexane:ethyl acetate:2 M NH3 in MeOH=20:5:1) to provide the product. Add excess 1 N HCl in diethyl ether (1 mL, 10 mmol) to the isolated product and remove the solvent to provide the title compound (150 mg, 84%). ES/MS m/z 539.0 (M+1).
