Participants

Reaction Steps

1.85 g (R)-1-(2-chloro-6-methyl-3-nitropyridin-4-yl)piperidine-3-carbamic acid tert-butyl ester (5 mmol) was dissolved in 10 mL N-methylpyrrolidone, to which 1.4 mL triethylamine (10 mmol) was added, and 1.25 g 2,4-dimethoxybenzylamine (7.5 mmoL) was added. The reaction was continued for 24 h at 80° C. The reaction solution was exacted three times with ethyl acetate. The ethyl acetate phase was combined, washed three times with water, dried, and evaporated to dryness. The resultant crude product was purified through a column chromatography (ethyl acetate:petroleum ether=1:8) to afford 1.83 g titled product with a yield of 73.1%.
