Reaction Steps
A 0° C. solution of ethyl 6-chloro-4-(methylamino)nicotinate (4 g, 18.7 mmol) in THF (40 mL), under a N2 atmosphere, was treated portion-wise with LiAlH4 (1.4 g, 37.4 mmol), stirred for 20 min, then carefully treated with water followed by 2 N NaOH. The suspension was filtered and the filtrate was concentrated to afford (6-chloro-4-(methylamino)pyridin-3-yl)methanol (2.9 g, 91% yield), which was used in next step without purification. 1H NMR (400 MHz, DMSO-d6): δ 7.96 (s, 1H), 6.63 (s, 1H), 6.46 (s, 1H), 5.04 (s, 1H), 4.39 (m, 2H), 2.81-2.68 (m, 3H).
