Pyridine → 6-(morpholin-4-yl)-2-{2-oxo-2-[4-(1-propylpiperidin-3-yl)-2,3-dihydro-1H-indol-1-yl]ethyl}pyrimidin-4(3H)-one

Participants

Reaction Steps

0.2 ml of pyridine, 25.7 mg of 4-(1-propylpiperidin-3-yl)-2,3-dihydro-1H-indole (reference example 4d) and 17.8 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride are successively added to a solution of 20.5 mg of sodium [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate (example 1d, step 2d) in 0.8 ml of N,N-dimethylformamide. The reaction mixture is stirred at ambient temperature for 24 hours, and then concentrated under reduced pressure. The residue is taken up in 10 ml of water and then extracted with dichloromethane (4×20 ml). The organic phases are combined and then washed with water and concentrated under reduced pressure. After oven-drying, 16.1 mg of 6-(morpholin-4-yl)-2-{2-oxo-2-[4-(1-propylpiperidin-3-yl)-2,3-dihydro-1H-indol-1-yl]ethyl}pyrimidin-4(3H)-one are obtained in the form of a pink solid, the characteristics of which are the following:
