In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 2613-30-1 as follows. HPLC of Formula: C6H4ClF2N

Anhydrous copper (II) bromide (2.7 g, 12.1 mmol) and t-butyl nitrite (1.56 g, 15.1 mmol) were combined in anhydrous acetonitrile (25 mL). The resulting mixture was heated to 65 C. and a solution of 4-chloro-2,5-difluoro-phenylamine (1.65 g, 10.1 mmol) in anhydrous acetonitrile (2 mL) was added dropwise (vigorous gas evolution was noted). After the reaction mixture cooled to ambient temperature, it was added to 2N HCl and extracted twice with diethyl ether. The organic extracts were then combined, washed with 2N HCl, washed with saturated sodium bicarbonate, dried, concentrated and purified by flash chromatography on silica gel (hexanes) to give the title compound as a white solid (1.11 g, 48.4% yield): 1H NMR (CDCl3) delta 7.38 (dd, 2H), 7.21 (dd, 2H).

According to the analysis of related databases, 2613-30-1, the application of this compound in the production field has become more and more popular.

Reference of 2613-30-1, A common heterocyclic compound, 2613-30-1, name is 4-Chloro-2,5-difluoroaniline, molecular formula is C6H4ClF2N, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

General procedure: To a solution of 1H-pyrrolo[3,2-H]quinoline-3-sulfonyl chloride (140 mg, 0.52 mmol) in pyridine (1.5 mL) was added 4-chloro-2,5-difluoroaniline (90 mg, 0.55 mmol). The reaction mixture was stirred at room temperature for 4h and then evaporated to dryness. The residue was triturated in a mixture of water/acetonitrile (8/2) and sonicated. The solid suspension was filtered, rinsed with water, dried under vacuum at 35C, to afford 105 mgof N-(4-chloro-2,5-difluorophenyl)-1 H-pyrrolo[3,2-h]quinoline-3-sulfonamide 1-118, as a beige solid.Yield: 50%.Basic LCMS Method 1 (ES): 394 (M+H), 99 % purity.1H NMR (400 MHz, DMSO-d6) 6 13.26 (s, 1H), 10.51 (s, 1H), 8.93 (dd, J = 4.4, 1.6 Hz,1 H), 8.46 (dd, J = 8.3, 1.6 Hz, 1 H), 8.04 – 7.65 (m, 3H), 7.59 (m, 1 H), 7.51 (dd, J = 9.8,6.8 Hz, 1H), 7.40 (dd, J = 10.4, 7.0 Hz, 1H).
