실험 절차
To a stirred solution of 6-bromo-3,4-dihydroquinolin-2(1H)-one (74-3; 15.0 g, 0.066 mol) in toluene (150 mL) was added Lawesson's reagent (13.4 g, 0.033 mol). Reaction mass was refluxed at 100° C. for 3 h. The reaction mixture was concentrated and directly purified by silica gel column chromatography to obtain title compound. MS (M+2): 243.9.
