Reaction Steps

Sodium iodine (catalytic amount) and potassium carbonate (65 mg, 0.47 mmol) were added to a solution of N-butyl-N-(6-(4-chlorobutyl)-3-mesityl-2,5-dimethylpyrazolo[1,5-a]pyrimidin-6-yl)amine (65 mg, 0.15 mmol) in 1-methyl-2-piperidone (2 mL), followed by stirring at 150° C. for four hours. Then, the mixture was treated with water, extracted with ethyl acetate, dried over anhydrous magnesium sulfate and evaporated. The residue was purified by silica gel chromatogrpahy (15% ethyl acetate/hexane), to give the title compound (18 mg) as yellow crystals.
