Dimethylformamide → HCID 12021991, compound

Participants

Reaction Steps

2.1 g of 7-(4,6-dimethoxypyrimidin-2-yl)-4-(2-furyl)-7-hydroxyfuro[3,4-b]pyridin-5(7H)one was weighed out, and 50 ml of N,N-dimethylformamide and 0.82 g of potassium carbonate were added thereto. The mixture was stirred at room temperature. 0.8 g of methyl iodide was added thereto dropwise, and the mixture was stirred at room temperature overnight, then poured into water and extracted 200 ml of ethyl acetate. The extract was washed with saturated aqueous sodium chloride solution and dried over anhydrous magnesium sulfate. The solvent was distilled off, and the residue was purified by silica gel column chromatography (developing solvent: ethyl acetate/hexane=1/3) to obtain 1.1 g (yield 50.7%) of the desired compound as brown crystals. m.p.: 135°-140° C.
