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 4-(2-aminoethyl)morpholine (32 mg, 0.25 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC. HCl) (38 mg, 0.20 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 using chromatography (silica gel, gradient 10% MeOH/ethyl acetate) yielding Compound 50 as a solid (10 mg).
