3-(5-Amino-2,4-difluorophenyl)-7-chloro-1-methyl-1,6-naphthyridin-2(1H)-one (2.4 g, 7.5 mmol) and 4-methoxy-N-methylbenzylamine (10 mL) were combined in a sealed vessel and heated to 200° C. overnight. The volatiles were removed in vacuo and the residue was purified by column chromatography to give 7-(4-methoxybenzyl)(methyl)amino)-3-(5-amino-2,4-difluorophenyl)-1-methyl-1,6-naphthyridin-2(1H)-one (3 g, 91% yield), which was used in the next step without further purification.
