反应详情

2 g of 1-(4-fluoro-2,3-dihydroindol-1-yl)-2-(4-methoxy-6-chloropyrimidin-2-yl)ethanone are added to a microwave tube with 30 ml of acetonitrile. 3.1 g of KI and 2.4 ml of trimethylchlorosilane are added. After microwave irradiation for one hour at a temperature of 100° C., the reaction medium is diluted with 100 ml of ethyl acetate and 20 ml of water. After settling out, the organic phase is dried over magnesium sulfate, filtered, and then concentrated under reduced pressure. The residue obtained is purified on a silica column, eluent: 95/05 dichloromethane/methanol, so as to give 1.13 of 2-[2-(4-fluoro-2,3-dihydroindol-1-yl)-2-oxoethyl]-6-chloro-3H-pyrimidin-4-one in the form of a white solid.
