63069-50-1, 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 63069-50-1 as follows.
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).
