Reaction Steps

Phenyl isocyanate (58 mg, 0.488 mmol) was added to a solution of Example A7 (200 mg, 0.444 mmol) and pyridine (140 mg, 1.776 mmol) in THF (5 mL) and the mixture was stirred at RT overnight. The mixture was diluted with EtOAc, water and satd. NaHCO3; the resulting precipitate was collected by filtration, washed with EtOAc and dried in vacuo to give 1-(5-(7-((4-methoxybenzyl)(methyl)amino)-1-ethyl-2-oxo-1,2-dihydro-1,6-naphthyridin-3-yl)-2,4-difluorophenyl)-3-phenylurea (219 mg, 87% yield).
