Reaktionsschritte
The mixture of ethyl 2,4-dichloropyrimidine-5-carboxylate (332 mg, 1.50 mmol), 1-Boc-3-aminomethylpyrrolidine (300 mg, 1.50 mmol) and DIEA (0.650 mL, 3.73 mmol) in CH3CN (6 mL) was stirred at room temperature for 18 h. Water and EtOAc were added. The organic phase was separated, washed with 1N HCl, then with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo to give ethyl 4-((1-(tert-butoxycarbonyl)pyrrolidin-3-yl)methylamino)-2-chloropyrimidine-5-carboxylate (544 mg).
