6-(tert-Butoxycarbonyl-ethyl-amino)-nicotinic acid (6.40 g, 24.0 mmol) is taken up in 150 mL DCE, 1-chloro-N,N-2-trimethylpropenyl-amine (6.42 mL, 48.1 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.
