YieldReaction ConditionsOperation in experiment
60 g A) N-(6-Chloropyridin-2-yl)-beta-alanine A mixture of 2-amino-6-chloropyridine (100 g), methyl acrylate methyl acrylate (117 g) and acetic acid (34 mL) was stirred at 120C for 72 hours. The reaction was cooled to room temperature. Then, a 6 N aqueous sodium hydroxide solution (375 mL) was added thereto, and the mixture was stirred under conditions of heating to reflux for 5 hours. The reaction mixture was cooled to room temperature, and then, unreacted 2-amino-6-chloropyridine starting material was extracted with diethyl ether. The remaining aqueous layer was adjusted to pH = 4 to 5 with 3 N hydrochloric acid, and the precipitate was collected by filtration. The solid collected by filtration was dissolved in ethyl acetate, washed with saturated brine and dried over anhydrous sodium sulfate. Then, the solvent was distilled off under reduced pressure to obtain the title compound (60 g). 1HNMR (300 MHz, MeOD) delta 2.58 (2H, t, J = 6.8 Hz), 3.54 (2H, t, J = 6.8 Hz), 6.38 (1H, dd, J = 8.4, 0.6 Hz), 6.49 (1H, dd, J = 7.2, 0.6 Hz), 7.33 (1H, dd, J = 8.4, 7.4 Hz).

YieldReaction ConditionsOperation in experiment
With eaton's reagent; at 75.0℃; for 3h; B) 7-Chloro-2,3-dihydro-1,8-naphthyridin-4(1H)-one A mixture of <strong>[76629-11-3]N-(6-chloropyridin-2-yl)-beta-alanine</strong> (40 g) and Eaton's Reagent (600 mL) was stirred at 75C for 3 hours. The reaction mixture was poured to ice water and basified to pH = 10 with sodium hydroxide, followed by extraction with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate) to obtain the title compound. MS: [M+H]+ 182.8.
