HCID 86664608(5-Chlorocarbonyl-pyridin-2-yl)-methyl-carbamic acid tert-butyl ester

実験手順

6-(tert-Butoxycarbonyl-methyl-amino)-nicotinic acid (12.5 g, 47.0 mmol) [prepared analogously to A-05 using methylamine in stead of ethylamine] is taken up in 300 mL DCE, 1-chloro-N,N-2-trimethylpropenyl-amine (10.0 mL, 74.8 mmol) is added and the reaction mixture is stirred overnight at RT. The reaction mixture is concentrated under reduced pressure and the crude product is used in the next step without purification.
