Reaction Conditions

Reaction Steps

To a nitrogen purged solution of mL Pd2(dba)3 (10.19 g, 11.12 mmol), 5-(benzyloxy)-2-chloropyridine (48.87 g, 222.5 mmol), (2-diphenyl)dicyclohexyl-phosphine (7.797 g, 22.25 mmol) and THF (700 mL) was added lithium hexamethyl disilazide (267.0 mL, 267.0 mmol). The reaction was heated at 65° C. overnight and cooled to ambient temperature. 1M HCl (250 mL) was added and stirred for 30 minutes. Saturated sodium bicarbonate was added slowly. The mixture was extracted several times with CH2Cl2, dried, filtered, and concentrated to give the title compound (52.1 g, 98.94% yield).
