실험 절차

To a solution of 0.73 g (3 mmol) of 2-chloro-4-(cyclopentylamino)-5-nitropyrimidine and 0.49 g (4 mmol) N,N-dimethylaniline in 10 mL THF is added a solution of 0.94 g (3.4 mmol) of 1-(tert-butoxycarbonyl)-4-(4-aminophenyl)-piperazine in 20 mL of 2-propanol, and the resulting mixture is heated under reflux for 2 hours. After cooling and acidification with acetic acid, the mixture is diluted with water to give 1.37 g (94%) of the title compound: mp (MeOH) 194–196° C.
