Reaction Steps

To a solution of 180 mg ethyl 3-[(5-amino-6-chloropyridin-3-yl)amino]-2-(3-chloro-2,4,5-trifluorobenzoyl)acrylate in 3 ml N,N-dimethylformamide was added 57 mg of potassium carbonate, and the mixture was stirred at room temperature for 2 hours. The reaction solution was poured into ice water, and extracted by adding ethyl acetate. The organic layer was separated and dried over magnesium sulfate, and the solvent was distilled off. The solid content was collected by filtration to obtain 125 mg of the title compound as a pale yellow powder.
