Participants

Reaction Steps

6-chloro-4-((3-(trifluoromethyl)phenyl)amino)-1,5-naphthyridine-3-carbaldehyde (0.75 g, 2.13 mmol) was dissolved in ethanol (20 mL), added 1.2 mL of a solution of methylamine in ethanol (concentration 27%), stirred at room temperature for 4 h, and then added sodium borohydride (0.82 g, 21.7 mmol) to the system, continued stirring at room temperature for 18 h. The reaction was quenched with a saturated aqueous solution of sodium carbonate, concentrated under reduced pressure to remove ethanol, extracted with 80 mL of dichloromethane, the organic layer was dried over anhydrous sodium sulfate, concentrated under reduced pressure to obtain 0.77 g of the titled compound.
