Participants

Reaction Steps

To a 0° C. solution of ethyl 6-chloro-4-(methylamino)nicotinate (4 g, 18.7 mmol, from Example C3) in THF (40 mL) was added LiAlH4 (1.4 g, 37.4 mmol) portionwise under a N2 atmosphere. After stirring for 20 min, the reaction was quenched by cautious addition of water followed by aqueous solution of 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, 90.6% yield), which was used in next step without purification. 1HNMR (400 MHz, DMSO-d6): δ 7.96 (s, 1 H), 6.63 (s, 1 H), 6.46 (s, 1 H), 5.04 (s, 1 H), 4.39 (m, 2 H), 2.81-2.68 (m, 3 H).
