Reaction Steps

To a solution of 3-aminopyridin-2-ol (8.05 g, 73.0 mmol) in DCM (20 mL) was added CbzCl (13.2 mL, 93.0 mmol) and Na2CO3 (18.0 g, 170 mmol). The mixture was stirred at room temperature overnight. Ethyl acetate (500 mL) was added and the mixture was washed with NaHCO3 (50 mL). The organic phase was dried over MgSO4, filtered and concentrated. The crude product was purified by combi-flash (ISCO, 40 g silica, MeOH/DCM from 3% to 5%, UV254) to afford benzyl (2-hydroxypyridin-3-yl)carbamate (16.2 g, 90% yield): MS (ES) m/z 245 (M+H).
