Procedure

To a solution of 4-(7-bromo-1,5-naphthyridin-4-yloxy)benzenamine (0.150 g, 0.474 mmol) in MeOH (7 mL) at RT was added a suspension of 10% palladium on carbon (0.0505 g, 0.474 mmol) in EtOAc (2 mL). The mixture was subjected to an atmosphere of hydrogen (balloon) and stirred overnight. After 18 hrs, the mixture was filtered over celite and concentrated in vacuo. The resulting tan foam, crude 4-(5,6,7,8-tetrahydro-1,5-naphthyridin-4-yloxy)benzenamine, was advanced without further purification. [email protected] min
