Reaction Steps

3-Chloro-6-(pyridin-2-ylmethoxy)pyridazine (Example 15a) (221 mg, 1 mmol) was dissolved in toluene (10 mL), EtOH (2 mL), and water (1.5 mL). Then 2,4-dimethylphenylboronic acid (150 mg, 1 mmol) was added, followed by K2CO3 (276 mg, 2 mmol) and the mixture was degassed using argon stream. Tetrakis(triphenylphosphine)palladium (232 mg, 0.2 mmol) was added under argon and the mixture was refluxed overnight. The solvents were removed under vacuum and a residual solid was extracted with EtOAc, and successively washed with water and brine dried over MgSO4 filtered and evaporated. The crude material was purified on silica gel (Eluent: 50% EtOAc in hexanes) to give 3-(2,4-Dimethylphenyl)-6-(pyridin-2-ylmethoxy)pyridazine (169 mg, 58%) as a white solid. 1H NMR (300 MHz, dMSO): δ 2.26 (s, 3H), 2.32 (s, 3H), 5.62 (s, 2H), 7.13-7.15 (m, 2H), 7.28-7.40 (m, 2H), 7.55-7.56 (d, 1H), 7.78-7.84 (m, 2H), 8.58-8.60 (d, 1H); MS (M+H, 292).
