Reaction Steps
A solution of 2-chloronicotinic acid (2.0 g, 12.6 mmol) in THF (15 mL) at 0° C. was treated dropwise with 1M LAH in THF (15 mL, 15.0 mmol), warmed to room temperature, stirred for 5 hours, treated sequentially with water (0.5 mL), 40% NaOH solution (0.5 mL) and water (1.5 mL), stirred for 2 hours, filtered through a pad of diatomaceous earth (Celite®), and extracted with dichloromethane. The combined extracts were dried (MgSO4), filtered, and concentrated to provide 1.56 g (87%) of the desired product of sufficient purity for subsequent use. MS (DCI/NH3) m/z 144 (M+H)+; 1H NMR (CDCl3) δ 8.34 (dd, 1H), 7.90 (m, 1H), 7.29 (dd, 1H), 4.80 (s, 2H).
