Reaction Conditions

Reaction Steps

A mixture of 2-amino-8-quinolinol (3.20 g, 20.0 mmol), ethylene carbonate (1.76 g, 20.0 mmol) and KO-t-Bu (2.24 g, 20.0 mmol) in DMF (20 mL) was stirred at 90° C. for 15 h The mixture was poured into brine, extracted with EtOAc, dried (MgSO4), and concentrated under reduced pressure. The residue was purified by chromatography on silica gel using toluene/EtOAc/MeOH (50:50-2) as eluent to give 1.13 g (28%) of the title product as a solid HRMS m/z calcd for C11H12N2O2 (M)+ 204.0899. found 204.0906
