Reaction Steps

A mixture of 5-bromo-N-(4-fluorobenzyl)-8-hydroxy-[1,6]naphthyridine-7-carboxamide (2.00 g, 5.33 mmol), tri-n-butylvinyl tin (3.12 mL, 10.70 mmol), bis (triphenylphosphine)palladium(II) chloride (0.75 g, 1.10 mmol), N-Boc-ethylenediamine (4.23 g, 26.6 mmol) in dioxane (50 mL) was purged with nitrogen and heated with stirring at 100° C. in a sealed tube overnight. The resultant product mixture was filtered through a pad of Celite. The filtrate was concentrated under vacuum. The residue was dissolved in DMSO, and subjected to HPLC purification on C-18 stationary phase eluted with water/acetonitrile/TFA mobile phase. Collection and lyophilization of appropriate fractions provided the title N-Boc amino napthyridine.
