Reaction Steps

A suspension of 4-bromo-2-bromomethyl-5-methoxy-pyridine (Step AL2) (1.2 g, 4.3 mmol), KCN (417 mg, 6.4 mmol) and aliquat 336 (35 mg, 0.085 mmol) in H2O was stirred at 50° C. for 2 h. The reaction mixture was dissolved in CH2Cl2, extracted with a saturated aqueous solution of NaHCO3, washed with brine, dried (Na2SO4), filtered and concentrated. The crude product was purified by silica gel column chromatography (hexane/EtOAc, 100:0→1:1). tR: 3.83 min (HPLC 7).
