実験手順
6-(tert-Butoxycarbonyl-methyl-amino)-nicotinic acid (12.5 g, 47.0 mmol) (prepared analogously to A-08 using methyl amine instead 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.
