Procedure
To a suspension of 2-(4-chloro-3,5-diphenyl-1H-pyrazolo[3,4-c]pyridazin-1-yl)acetic acid (60 mg, 0.16 mmol) in DMF (1 mL) were added 1-methyl-4-(methylamino)piperidine (23 mg, 0.18 mmol), diisopropylethylamine (DIPEA) (63 μL, 0.36 mmol) and 2-(7-aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) (75 mg, 0.20 mmol). The solution obtained was stirred at room temperature for 1 hr then diluted with EtOAc. The organic phase was washed with water and brine, dried (MgSO4) and concentrated in vacuo. The resultant residue was purified using chromatography (silica gel, gradient 1% Et3N in 10-20% MeOH/ethyl acetate) yielding Compound 51 as a solid (2 mg).
