Reaction Conditions

Reaction Steps

4 mg acetyl chlorid are added at 0° C. to a suspension of 80 mg aluminium chloride 1,2-dichloroethane, followed by 208 mg 2-(3-Methoxy-6-pyridin-4-yl-pyridazin-4-yl)-1H-indole trifluoroacetate. The reaction mixture is stirred for 4 h at room temperature and for 3 h at 50° C. It is worked up pouring into an ice/water mixture and filtration. The layers are separated, the organic is layer washed with Water, dried over MgSO4 and the solvent removed. Reversed phase HPLC chromatography yielded 8.1 mg 4-(3-acetyl-1H-indol-2-yl)-6-pyridin-4-yl-2H-pyridazin-3-one
