PROCEDURE
实验过程
A solution of N-(4-bromo-pyridin-3-yl)-N-methyl-3,5-bis-trifluoromethyl-benzamide (example 25, intermediate a) (200 mg, 0.468 mmol), 3,6-dimethoxylpyridazine-4-boronic acid (129 mg, 0.702 mmol, CAS RN 1015480-87-1) and K2CO3 (194 mg, 1.404 mmol) in DMF (6 mL) in a sealed tube was degassed with argon for 30 minutes. To this mixture were added S-PHOS (96 mg, 0.234 mmol, CAS RN 657408-07-6) and Pd(PPh3)4 (44 mg, 0.046 mmol), degassed for another 15 minutes, and heated to 90° C. for 1 h in microwave. Work up and purification as described in example 25 yielded 15 mg of the title compound. Off-white solid (7%). MS (ESI): m/z=487.0 [M+H]+.
