실험 절차
To a stirred solution of 6-bromo-5-chloro-3,4-dihydroquinoline-2(1H)-thione (143-6; 0.3 g, 0.0012 mol) in n-butanol (10 mL) was added acetic hydrazide (0.2 g, 0.00213 mol). Reaction mass was heated at 120° C. for 16 h. The reaction mixture was concentrated and directly purified by silica gel column chromatography to obtain title compound. MS (M+1): 298.0.
