HCID 816462(1H)-Pyrimidinone, tetrahydro-1,3-dimethyl-Solvent

Procedure

To a solution of 5-bromo-N-(3,5-dichlorobenzyl)-8-hydroxy-1,6-naphthyridine-7-carboxamide from Example 50 (26 mg, 0.068 mmol), phenol (28 mg, 0.304 mmol) and cesium carbonate (198 mg, 0.608 mmol) in DMPU (0.25 ml) was heated at 140C for 8 hrs. The reaction was poured into sat aq. Na2CO3 and extracted with CHCl3. The organic phase was washed with water and dried (Na2SO4). The solvent was evaporated in vacuo and the residue dissolved in DMF (0.7 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.
