Reaction Steps

BuLi (5.84 mL, 9.35 mmol) was added to a solution of 3-bromo-4-diethoxymethyl-pyridine (2.21 g, 8.50 mmol) in THF (50 mL) at −78° C. After 1 h, DMF (6.58 mL, 85 mmol) was added. The reaction was stirred at −78° C. for 1 hr. It was then warmed to room temperature, quenched with water and extracted with ethyl acetate. The organic layer was dried over sodium sulfate and concentrated in vacuo to afford 1.4 g of 4-diethoxymethyl-pyridine-3-carbaldehyde, which was taken in the next step without further purification.
