PROCEDURE
实验过程
N-[3-(5-Iodo-imidazo[2,1-b][1,3,4]thiadiazol-2-yl) -benzyl]-methanesulfonamide (77 mg, 0.177 mmol, 1 eq) was dissolved in 1,4-dioxane (3 mL) and 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3-trifluoromethyl-pyridin-2-ylamine (76 mg, 0.265 mmol, 1.5 eq), K2CO3 (73 mg, 0.531 mmol, 3 eq), H2O (2 mL) and dichlorobis(triphenylphosphine)palladium(II)(12 mg, 0.0177 mmol, 0.1 eq) were added. The reaction mixture was heated in a pressure tube at 105° C. overnight. Solvents were removed and the residue obtained was suspended in water and extracted twice with EtOAc. The organic layers were dried, filtered end evaporated. The residue was triturated with CH3CN and filtered. The solid was purified in an Isolute Si II cartridge (DCM/MeOH, 0%-5%). The product obtained was precipitated in CH3CN and filtered to give the desired product (5 mg, 6%). HPLC-MS (5-100% B in 8 min at 0.8 mL): tR=4.70 min, [M+H]+ m/z 469.1; 1H NMR (300 MHz, DMSO) δ 8.88 (s, 1H), 8.35 (s, 1H), 7.95 (s, 1H), 7.90 (m, 1H), 7.80 (s, 1H), 7.73 (t, J=6.3 Hz, 1H), 7.62 (d, J=4.7 Hz, 2H), 6.74 (s, 2H), 4.29 (d, J=6.3 Hz, 2H), 2.93 (s, 3H).
