Reaktionsschritte

Piperazine (2.0 g, 23 mmol) and N-methylpyrrolidone (10 ml) were added to 5-(8-chloro-9-isobutyl-6-morpholin-4-yl-9H-purin-2-yl)pyrimidin-2-amine (1.0 g, 2.6 mmol) and the resulting mixture was stirred at 130° C. for 4 hours. The reaction mixture was cooled and partitioned with methylene chloride and water, the organic layer was dried over magnesium sulfate, and the solvent was concentrated under reduced pressure. This compound (10 ml in liquid) was stored with N-methylpyrrolidone remaining and used for next step.
