반응 단계
1.5 g piperazine-1-carboxylic acid tert-butyl ester was added to 1.2 g 2-chlor-5-methoxy-pyrimidine and 2.2 mL triethylamine in 30 mL DMF. The reaction was stirred 6 days at 60° C. The solvent was removed and the residue was dissolved in dichlormethane and extracted with water. The organic layer was washed with a saturated sodiumchloride-solution and evaporated. The residue was purified by HPLC to give 957 mg desired product.
