Reaktionsschritte
To a solution of ethyl 4-((1-(tert-butoxycarbonyl)pyrrolidin-3-yl)methylamino)-2-chloropyrimidine-5-carboxylate (544 mg, 1.41 mmol) in THF (8 mL), aq. 1N NaOH (8 mL, 8.0 mmol) was added. The mixture was stirred at room temperature for 18 h. It was acidified to pH 1-2 with 6N HCl. Water and EtOAc were added. The organic phase was separated, washed with brine, dried over Na2SO4, concentrated in vacuo to give 4-((1-(tert-butoxycarbonyl)pyrrolidin-3-yl)methylamino)-2-chloropyrimidine-5-carboxylic acid (503 mg).
