Procedure

To a suspension of 2-(4-chloro-3,5-diphenyl-1H-pyrazolo[3,4-c]pyridazin-1-yl)acetic acid (56 mg, 0.15 mmol) in DMF (1 mL) were added N1,N1,N2-trimethylethane-1,2-diamine (17 mg, 0.17 mmol), diisopropylethylamine (DIPEA) (59 pt, 0.34 mmol) and 2-(7 -aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) (70 mg, 0.18 mmol). The solution obtained was stirred at room temperature for 18 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 preparative HPLC yielding Compound 53 as a solid (11 mg).
