実験手順

2-(4-piperazin-1-yl-phenyl)-pyrimidine (compound 10 from Step 7, 14.7 mmol) and 1-Carboxymethyl-pyrrolidine-3-carboxylic acid methyl ester (compound 5 from Step 3, 17.6 mmol) were dissolved in 72 ml of DMF. Triethylamine (8 ml, 57 mmol), 1-hydroxybenztriazole (2.29 gm) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDCl) (3.43 gm, 18 mmol) were added and the reaction mixture stirred for 24 hrs. After washing with brine, extracting with dichloromethane, and drying over magnesium sulfate, the mixture was evaporated and chromatographed on silica gel to obtain 5.0 gm of title product.
