Reaction Steps

tert-Butyl(4-chloro-3-formylpyridin-2-yl)carbamate (2.0 g, 7.79 mmol), 2-aminoethanol (0.57 g, 9.35 mmol), and AcOH (0.47 g; 7.79 mmol) were suspended in toluene (20 mL), and stirred overnight at room temperature. The reaction mixture was concentrated, and suspended in hexanes/ether (5/1, v/v). The resulting precipitate was filtered, suspended in NMP (3 mL) in 20 ml seal tube, and heated for 30 min. at 150° C. The crude product was purified directly via HPLC to provide 42 (270 mg, 10% yield) as a solid. LC-MS (M+H=226, obsd.=226).
