Participants

Reaction Steps

A solution of 5-bromo-N-(4-fluorobenzyl)-8-hydroxy-1,6-naphthyridine-7-carboxamide (0.25 g, 0.67 mmol), thiomorpholine (0.19 mL, 2.0 mmol) and diisopropylethylamine (0.06 mL, 0.67 mmol) in DMPU (3.0 mL) were heated at 135 C for 23 hr. The reaction was cooled to room temperature, neutralized by the addition of TFA and purified by reverse phase HPLC. (Vydak C18, Gradient elution with Water:Acetonitrile 95:5 to 5:95 with 0.1% TFA at 30 mL/min over 15 mins). Lyophilization of the pure fractions afforded the title compound as an off white solid.
