Reaction Steps

To a mixture of 4-(1-ethylpropyl)-5-(4-isoxazol-3-ylphenyl)-3-(6-methoxypyridin-3-yl)-4,5-dihydro-1H-pyrrolo[3,4-c]pyrazol-6-one (0.067 g, 0.15 mmol) and sodium iodide (0.067 g, 0.45 mmol) in acetonitrile (3 mL) was added chlorotrimethylsilane (0.058 mL, 0.45 mmol). The mixture was heated under reflux with stirring for 1 h. Water (50 mL) and ethyl acetate (50 mL) were added to the mixture, and the precipitate was collected by filtration and dried to give 4-(1-ethylpropyl)-5-(4-isoxazol-3-ylphenyl)-3-(6-oxo-1,6-dihydropyridin-3-yl)-4,5-dihydro-1H-pyrrolo[3,4-c]pyrazol-6-one (0.041 g, 64%) as slightly yellow crystals.
