Reaction Steps
To a magnetically stirred solution of 4.0 mL of approximatly 2.0M LDA solution (in hexane) (7.98 mmol) was added a solution of 2,6-dimethoxyl-3-bromopyridine (3.14 g, 6.14 mmol) in 10 mL of THF at -78° C. over a period 20 minutes while the internal temperature was kept below -78° C. To the resulting red-brown suspension was added a solution of chlorodiphenylphosphine (1.20 mL, 6.75 mmol) in the 10 mL of THF at -78° C. The reaction mixture was allowed to warm to ambient temperature overnight and was poured into 20 mL water. The organic product was extracted with dichloromethane (3×20 mL). The combined extract was dried with anhydrous magnesium sulfate and was concentrated in vaccuo to give a crude product which was recrystallized in methanol to give 2.34 g of pure product (95% theoretical yield).
