Reaction Steps

2-Aminobenzaldehyde (1.75 g, 14.5 mmol) was dissolved in xylene (87.5 mL). To this, ethyl 2-nitroacetate (6.43 mL, 58.0 mmol) and piperidine (1.58 mL, 16.0 mmol) were added and the mixture was stirred with heat at 150° C. for 1.5 hours and successively stirred with cooling in an ice bath for 0.5 hour. The precipitate was collected by filtration and dried under reduced pressure. Thus, 3-nitroquinolin-2(1H)-one (1.40 g, yield: 51%) was obtained.
