With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.205055-63-6,6-Bromo-1-chloroisoquinoline,as a common compound, the synthetic route is as follows.
Step 3. R-[4-Chloro-3-(5-phenyl-lH-imidazol-2-yl)-phenyl]-[6-(2-methyl- morpholin-4-yl)-isoquinolin-l-yl] -amine [0067] A mixture of l-chloro-6-bromo-isoquinoline (242 mg, 1.00 mmol), which is prepared according to literature procedure [1], R-2-methylmorpholine hydrochloride (138 mg, 1.00 mmol), Pd2(dba)3 (18.3 mg, 0.02 mmol), xantphos 34.7 mg, 0.06 mmol), and ?-BuONa (288 mg, 3.00 mmol) is subject to vacuo and backfilled with argon. Toluene (1.8 mL) is then added and the mixture was heated at 100 0C for 2 hours. After the reaction mixture is cooled to room temperature, it is directly loaded to a silica gel column and is chromatographed (DCM: EtOAC = 100 : 3) to give l-chloro-6-(2-R- methyl-morpholin-4-yl)-isoquinoline as an oil.[0068] A mixture of l-chloro-6-(2-R-methyl-morpholin-4-yl)-isoquinoline (26.3 mg, 0.1 mmol), 4-chloro-3-(5-phenyl-l//-imidazol-2-yl)-phenylamine (27.0 mg, 0.1 mmol), Pd2(dba)3 (9 mg, 0.01 mmol), xantphos 17 mg, 0.03 mmol), and K3PO4 (64 mg, 0.3 mmol) is subject to vacuo and backfilled with argon. 1,4-Dioxane (0.4 mL) is then added and the mixture is heated under stirring at 96 0C overnight. After it is cooled to room temperature, the reaction mixture is redistributed between ethyl acetate (30 mL) and saturated solution of ammonium chloride (30 mL). The organic phase is separated, dried with Na2SO4, and evaporated to give a residue which is subject to reverse -phase preparative LC-MS (acetonitrile/water/TFA gradient 10-90 % CH3CN in 7.5 min, Ultro 120 5uM C18Q, 75x30mmID). The collected water/MeCN solution of the TFA salt of the product is evaporated to remove the acetonitrile. A saturated aqueous solution of NaHCO3 is added to raise the pH to 8-9. Then ethyl acetate is used to extract the product and the organic phase is dried with Na2SO4. Evaporation of the solvent yields the free- based R-[4-chloro-3-(5-phenyl-lH-imidazol-2-yl)-phenyl]-[6-(2-methyl-mophiholin-4-yl)- isoquinolin-l-yl]-amine. 1H NMR 400 MHz (MeOD) delta 8.19 (d, / = 9.2 Hz, IH), 7.97- 7.91 (m, IH), 7.79-7.71 (m, IH), 7.50 (s, IH), 7.44 (d, J = 8.8 Hz, IH), 7.40-7.31 (m, IH), 7.26-7.18 (m, IH), 7.05-7.01 (m, IH), 4.03-3.97 (m, IH), 3.90-3.64 (m, 4H), 2.92- 2.81 (m, IH), 2.58-2.50 (m, IH), 1.24 (d, J= 6.0 Hz, 3H). LRMS m/z 496.3 (MH+).
