Procedure
To a solution of 5-bromo-N-(3,5-dichlorobenzyl)-8-hydroxy-1,6-naphthyridine-7-carboxamide from Example 50 (25 mg, 0.060 mmol), N-methyl piperazine (35.2 mg, 0.35 mmol) in DMF (0.25 ml) was heated at 135C for 48 hrs. The reaction mixture was diluted with DMF (0.25 ml) and purified by preparative HPLC. (Gilson semi preparative HPLC system and a YMC Combiprep Pro Column (50×20 mm I.D., C18, S-5 um, 120A) eluting with 5-95% acetonitrile/water (0.1% TFA) at 15 ml/min) to afford the title compound after lyophilization.
