Cesium carbonate → 6-(4-(6-fluoropyridin-2-yl)benzyl)-1-isobutyl-3-methyl-1H-pyrrolo[3,4-d]pyrimidine-2,4(3H,6H)-dione

Participants

Reaction Steps

A suspension of 1-isobutyl-3-methyl-1H-pyrrolo[3,4-d]pyrimidine-2,4(3H,6H)-dione (540 mg, 2.46 mmol), 2-(4-(chloromethyl)phenyl)-6-fluoropyridine (0.60 g, 2.7 mmol) and cesium carbonate (1.6 g, 4.9 mmol) in anhydrous DMF is stirred at room temperature for 10 minutes. The mixture is diluted with 200 mL of water, and then extracted with CH2Cl2 three times. The combined organic phase is washed with brine, and then dried with anhydrous Na2SO4. After filtration, the filtrate is concentrated under vacuum. The residue is purified by silica gel chromatography to give product as pale yellow solids (705 mg, yield: 71%). MS (ESI) m/z 407.2 [M+H]+.
