Reaction Steps

To a suspension of (5-bromo-6-methoxy-pyridin-3-yl)-acetonitrile (Step AM1) (6.61 mmol) in EtOH (19 mL) was added a solution of KOH (26.7 mmol) in H2O (19 mL) and the mixture was stirred at 80° C. for 45 min. After cooling to rt, the pH was adjusted to 3-4 with 1M aqueous HCl and the mixture was extracted with CH2Cl2 (2×). The combined organic layers were dried (MgSO4), filtered and concentrated to afford the title compound. ESI-MS: tR=0.75 min, [M+H]+ 246/248 (LC-MS 1).
