Reaktionsschritte
A solution of methyl 4,6-dichloronicotinate (1.20 g, 5.8 mmol), tert-butyl 4-(aminomethyl)piperidine-1-carboxylate (1.24 g, 5.8 mmol) and triethylamine (4.09 mL, 29.1 mmol) in n-butanol (13 mL) was heated at 120° C. for 90 minutes by microwave irradiation. The solvent was evaporated and the mixture was purified by flash chromatography on silica, eluting with ethyl acetate-hexane (1:4), to give methyl 4-((1-(tert-butoxycarbonyl)piperidin-4-yl)methylamino)-6-chloronicotinate as a colourless solid (1.87 g, 84%).
