YieldReaction ConditionsOperation in experiment
3.33 g A solution of the compound 0001-2 (2.88 g) and sodium acetate (2.89 g) in acetic acid (15 mL) was stirred at 85C for 5 minutes. A solution of bromine (0.99 mL) in acetic acid (2.5 mL) was dropwise added thereto. Further acetic acid (2 mL) was added dropwise thereto, and the mixture was stirred at 85C for 3 hours. To a 6 M aqueous sodium hydroxide solution (60 mL) under stirring with ice-cooling, the reaction solution which had been cooled to room temperature was added dropwise. The precipitated solid was separated by filtration, and the solid was then suspended in methanol (5 mL), and thereafter subjected to sonication. Thereafter, the suspension was filtered, and then the resulting solid was washed with methanol (3 mL). The obtained solid was suspended in a 75 v/v% aqueous methanol solution (8 mL), subjected to sonication, and then the suspension was filtered, and the residue was then washed with a 75 v/v% aqueous methanol solution twice to obtain a compound 0001-3 (3.33 g) as a pale yellow solid. 1H-NMR (DMSO-d6) delta: 9.13 (1H, d), 8.77 (1H, dd), 8.53 (1H, dd), 7.91 (1H, d). MS m/z (M+H): 245.
3.33 g With bromine; sodium acetate; acetic acid; at 85℃; for 3h; 0001-3 A solution of bromine (0.99 mL) in acetic acid (2.5 mL) was added dropwise to a mixture of 2-chloro-1,5-naphthyridine (2.88 g) and sodium acetate (2.89 g) in acetic acid (15 mL) at 85 C., and acetic acid (2 mL) was added thereto, followed by stirring at 85 C. for 3 hours. The reaction mixture was cooled to room temperature, and added dropwise to a 6 mol/L sodium hydroxide aqueous solution (60 mL) under ice-cooling. The solid matter was collected by filtration, suspended in methanol (5 mL), and subjected to an ultrasonic treatment. The solid matter was collected by filtration, and washed with methanol (3 mL). The obtained solid was suspended in a 75 v/v % methanol aqueous solution (8 mL), the resultant product was subjected to an ultrasonic treatment, and the solid matter was collected by filtration, thereby obtaining 7-bromo-2-chloro-1,5-naphthyridine (3.33 g) as a pale yellow solid. MS m/z (M+H): 243.

YieldReaction ConditionsOperation in experiment
250 mg With N-ethyl-N,N-diisopropylamine; In 1-methyl-pyrrolidin-2-one; at 150℃; for 1h; 200 mg of compound 31, 200 mg of compound 6a, and 350 mg of DIEA were suspended in 10 ml of NMP, and heated to 150 C. and stirred for 1 h. After the TLC detection reaction was completed, cooled, added 40 ml of water, and extracted twice with ethyl acetate. The organic phases were combined, washed with water, dried, and purified by TLC (petroleum ether: ethyl acetate = 1: 1) to obtain 250 mg of intermediate 32.
