To a suspension of 2-(4-chloro-3,5-diphenyl-1H-pyrazolo[3,4-c]pyridazin-1-yl)acetic acid (100 mg, 0.27 mmol) in DMF (2 mL) were added 1-methyl-cyclobutyl amine hydrochloride (37 mg, 0.30 mmol), diisopropylethylamine (DIPEA) (150 μL, 0.60 mmol) and 2-(7-Aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) (125 mg, 0.33 mmol). The solution obtained was stirred at room temperature for 2 h then diluted with EtOAc. The organic phase was washed with water and brine, dried (MgSO4) and concentrated in vacuo. The resultant residue was purified by chromatography purification (silica gel, gradient 10-20% ethyl acetate/isohexane) yielding Compound 61 as a solid (22 mg).
