Procedure

The HCl salt of N-(4-(2-amino-3-chloropyridin-4-yloxy)-3-fluorophenyl)-5-(4-fluorophenyl)-4-oxo-1,4-dihydropyridine-3-carboxamide (Example 3) is obtained by treating a solution of N-(4-(3-chloro-2-(diphenylmethyleneamino)pyridin-4-yloxy)-3-fluorophenyl)-5-(4-fluorophenyl)-4-oxo-1,4-dihydropyridine-3-carboxamide (Preparation 3G) in THF with excess aqueous HCl at room temperature. The volatiles are removed in vacuo to provide the desired compound.
