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 6973-09-7 as follows. 6973-09-7
To a solution of Intermediate Example 4 (200 mg, 0.695 mmol) and 5-amino-2- methylbenzenesulfonamide (129.4 mg, 0.695 mmol) in isopropanol (6 ml) was added 4 drops of cone. HCI. The mixture was heated to reflux overnight. The mixture was cooled to rt and diluted with ether (6 ml). Precipitate was collected via filtration and washed with ether. The hydrochloride salt of 5-({4-[(2,3-dimethyl-2H-indazol~6- yl)(methyl)amino]-pyrimidin-2-yl}amino)-2-methylbenzenesulfonamide was isolated as an off-white solid. 1H NMR (400 MHz, d6DMSO+NaHCO3) delta 9.50 (br s, 1 H), 8.55 (br s, 1 H), 7.81 (d, J= 6.2 Hz, 1 H), 7.75 (d, J = 8.7 Hz1 1 H), 7.69 (m, 1 H), 7.43 (s, 1 H), 7.23 (S1 2H), 7.15 (d, J= 8.4 Hz1 1H), 6.86 (m, 1 H), 5.74 (d, J= 6.1 Hz, 1 H), 4.04 (s, 3H), 3.48 (S1 3H)1 2.61 (s, 3H)1 2.48 (s, 3H). MS (ES+, m/z) 438 (M+H).
