Reaction Steps

To 80 ml of chloroform were added 4.53 g of 4-[3-(1-acetylpiperidin-4-yl)propanoyl]aniline and 3.83 g of 4-chloro-5,6-dihydro-7H-cyclopenta[d]pyrimidine, and after adding 10 ml of a chloroform solution of hydrochloric acid (containing 0.9 g of hydrochloric acid), the mixture was refluxed under heating for 5 hours. After completion of the reaction, a 28% sodium methoxide was added to the mixture under ice cooling to make it alkaline and then the solvent was removed by distillation under reduced pressure. The obtained residue was applied to silica gel column chromatography to obtain 6.16 g of the title compound as brown powder.
