Potassium Carbonate → 3-Chloro-5-[3-[2-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-pyridin-4-ylmethyl]-5-isopropyl-2,6-dioxo-1,2,3,6-tetrahydro-pyrimidine-4-carbonyl]-benzonitrile

Participants

Reaction Steps

To a stirred solution of 3-Chloro-5-(5-isopropyl-2,6-dioxo-1,2,3,6-tetrahydro-pyrimidine-4-carbonyl)-benzonitrile (317 mgmg, 1 mmol), anhydrous powdered potassium carbonate (134 mg, 1 mmol), and lithium iodide (134 mg, 1 mmol) in DMF (5 ml) at room temperature, was added 2-(4-Chloromethyl-pyridin-2-yl)-isoindole-1,3-dione (272 mg, 1 mmol). After stirring for overnight, the mixture was evaporated in vacuo and the residue was purified by silica gel column chromatography (eluent, EA:hexanes (1:1); Rf˜0.3 fraction was collected.) to afford 160 mg (29%) of a white solid.
