Reaction Steps
To a solution of ethyl 6-chloro-4-(methylamino)nicotinate (4.7 g, 21.9 mmol) in THF (30 mL) and methanol (30 mL) was added lithium borohydride (2.4 g, 109.8 mmol), and the reaction mixture was heated at 55° C. overnight. LCMS showed the reaction was completed. The reaction was cooled to RT, quenched with water (1 mL) and filtered. The filtrate was concentrated to afford the title compound (4.2 g, crude) as a white solid, which was directly used in the next step without further purification. MS (ES+) C7H9ClN2O requires: 172, 174. found: 173, 175 [M+H]+.
