Reaction Steps

532 mg of hexahydrocyclopenta[1,4]oxazine hydrochloride are added to a solution of 100 mg of 2-[2-(4-fluoro-2,3-dihydroindol-1-yl)-2-oxoethyl]-6-chloro-3H-pyrimidin-4-one in 5 ml of diisopropylethylamine. The reaction medium is heated at 100° C. for 2 hours. The reaction medium is taken up with 10 ml of water. The solid formed is filtered off and washed with water and then dried so as to give 30 mg of 2-[2-(4-fluoro-2,3-dihydroindol-1-yl)-2-oxoethyl]-6-(hexahydrocyclopenta[1,4]oxazin-4-yl)-3H-pyrimidin-4-one in the form of a beige solid, the characteristics of which are the following:
