Participants

Reaction Steps

To a solution of compound (3-chloro-4-methoxy-phenyl)-(4,6-dichloro-pyrimidin-2-yl)-amine (0.08 g, 0.26 mmol) in butanol (3 mL) was added to cycloheptylamine (0.03 g, 0.26 mmol) at 25° C. with stirring. To this was added triethylamine (0.14 mL, 1.04 mmol), and the mixture was stirred for 30 minutes at 25° C. and then heated and refluxed for 12 hours under nitrogen atmosphere. The mixture was concentrated under vacuum, diluted with cold water, and extracted with ethyl acetate. The organic layers were collected, combined, washed with brine, dried over anhydrous sodium sulphate, and concentrated under vacuum to give the desired compound. Yield: 60%.
