Procedure
To a suspension of 2-(4-chloro-3-(4-fluorophenyl)-5-phenyl-1H-pyrazolo[3,4-c]pyridazin-1-yl)acetic acid (150 mg, 0.39 mmol) in CH2Cl2 (3 mL) were added morpholine (34 mg, 0.39 mmol), diisopropylethylamine (DIPEA) (200 μL, 1.2 mmol) and 2-(7-aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) (180 mg, 0.47 mmol). The solution obtained was stirred at room temperature for 75 min before being purified using chromatography (silica gel, gradient 20 to 100% ethyl acetate/isohexane) followed by preparative HPLC yielding Compound 75 as a clear glass solid (11.5 mg).
