실험 절차

A solution of 2,3-dihydro-1,4-dioxino[2,3-b]pyridin-6-amine (commercial; 2.70 g) in acetone/water 1:1 (40 mL) was treated at 0° C. with 1M NaHCO3 (35 mL) and CbzCl (2.63 mL). The reaction mixture was stirred at rt for 3 h, the org. solvent was evaporated under reduced pressure and the residue was partitioned between water and ether/EA. The org layer was dried over MgSO4 and evaporated under reduced pressure, affording a beige solid (5.3 g; 100% yield).
