Reaction Steps

A mixture of 5-bromo-N-(4-fluorobenzyl)-8-hydroxy[1,6]naphthyridine-7-carboxamide (0.99 g, 2.66 mmol), 1,2,5-thiadiazepan-4-one 1,1-dioxide from step 2 (0.41 g, 2.5 mmol) and copper (I) oxide (0.18 g, 1.25 mmol) in pyridine (13 mL) was heated in an oil bath at 115° C. overnight. The resultant mixture was treated with a mixture of chloroform (200 mL) and a saturated aqueous solution of ethylenediamine tetraacetic acid, disodium salt (200 mL) and stirred vigorously at room temp overnight in the presence of air. The slurry was filtered through a pad of Celite. The organic extract was separated, dried over anhydrous sodium sulfate, filtered and 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 compound.
