Reaction Steps

6-bromo-2-methyl-3-nitropyridine (2 g, 9.22 mmol) was dissolved in ethanol (20 mL) and to this solution was added ethanolamine (1.115 mL, 18.43 mmol). The reaction was left to stir overnight under nitrogen, at room temperature. The reaction was concentrated in vacuo, then diluted with ethyl acetate and saturated sodium bicarbonate solution. The organic phase was separated and washed with saturated sodium bicarbonate and brine, then dried using a hydrophobic frit and concentrated in vacuo to give the title compound as a yellow solid (1.68 g). Crude material used directly in next step, without further purification. LCMS (2 min, formic) Rt 0.60 min, m/z (ES+) 198 (M+H).
