Reaction Steps
To a solution of 1-indanol (60 mg, 0.45 mmol) in DMF (1 ml) was added sodium hydride (60% in oil, 18 mg, 0.45 mmol). The mixture was stirred for 10 min before addition of 4-chloro-1-(2,4-dimethylphenyl)-6-methyl-1,6-dihydro-7H-pyrrolo[2,3-d]pyridazin-7-one (43.2 mg, 0.15 mmol). The mixture was stirred at 60° C. for 3 hours, then diluted with water (30 ml) and extracted with ethyl acetate (30 ml×2). The extract were combined, washed with water, dried over magnesium sulfate and concentrated in vacuo. The residue was purified by silica gel chromatography eluting with hexane/ethyl acetate (10:1) to give 28 mg (48%) of the title compounds as an oil.
