Procedure

N-(4-((2-Aminopyridin-4-yl)oxy)-2,5-difluorophenyl)-4-ethoxy-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (0.12 g, 0.24 mmol) was dissolved in pyridine (2 mL), treated with isopropenyl chloroformate (0.030 mL, 0.27 mmol), and stirred at RT overnight. The solution was concentrated to obtain crude prop-1-en-2-yl (4-(4-(4-ethoxy-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamido)-2,5-difluorophenoxy)pyridin-2-yl)carbamate which was used for the next reaction (assuming 100% yield).
