Potassium Iodide → 2-[1-(4-fluoro-2,3-dihydro-1H-indol-1-yl)-1-oxopropan-2-yl]-6-(morpholin-4-yl)pyrimidin-4(3H)-one

Participants

Reaction Steps

210 mg of 1-(4-fluoro-2,3-dihydroindol-1-yl)-2-(4-methoxy-6-morpholin-4-yl-pyrimidin-2-yl)propan-1-one, 270 mg of potassium iodide, 7 ml of acetonitrile and 208 ml of trimethylchlorosilane are added to a microwave tube. After microwave irradiation for one hour at a temperature of 100° C., the reaction medium is diluted with 20 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 stirred in the presence of 5 ml of ethyl acetate and 20 ml of petroleum ether. The solid obtained is filtered off and then dried under reduced pressure. 163 mg of 2-[1-(4-fluoro-2,3-dihydro-1H-indol-1-yl)-1-oxopropan-2-yl]-6-(morpholin-4-yl)pyrimidin-4(3H)-one are thus obtained in the form of a pale yellow solid, the characteristics of which are the following:
