HCID 866136304,5-Bis-(4-chloro-phenyl)-2-(4-ethoxy-2-methyl-pyrimidin-5-yl)-4,5-dihydro-imidazole-1-carbonyl chloride

Procedure

Using the procedure as described in example 1, cis-4-[4,5-bis-(4-chloro-phenyl)-2-(4-ethoxy-2-methyl-pyrimidin-5-yl)-4,5-dihydro-1H-imidazole was reacted with phosgene to give cis-4-[4,5-bis-(4-chloro-phenyl)-2-(4-ethoxy-2-methyl-pyrimidin-5-yl)-4,5-dihydro-imidazole-1-carbonyl chloride. The carbonyl chloride was then coupled with 2-piperazinone (Alfa) to give cis-4-[4,5-bis-(4-chloro-phenyl)-2-(4-ethoxy-2-methyl-pyrimidin-5-yl)-4,5-dihydro-imidazole-1-carbonyl]-piperazin-2-one. HR-MS (ES, m/z) calculated for C27H27N6O3Cl2 [(M+H)+] 553.1516, observed 553.1515.
