실험 절차

To a solution of (4-bromo-pyridin-3-yl)-methyl-amine (50 mg, 0.267 mmol, example 25, intermediate b) and 3-methoxypyridine-4-boronic acid (CAS RN 1008506-24-8) (61.35 mg, 0.4 mmol) in dry DMF (3 mL) in a sealed tube was added potassium carbonate (2.14 mmol) and the reaction mixture was purged with argon for 10 min. Then, Pd(PPh3)4 (30.89 mg, 0.03 mmol) was added and again purged with nitrogen for 15 min. The reaction mixture was heated at 100° C. for 16 hours. After cooling to room temperature the reaction mixture was filtered through a bed of celite and the filter cake washed with EtOAc. The solvent was evaporated, the residue was dissolved in EtOAc and washed with water. The organic layer was dried over sodium sulphate and evaporated to get compound that was used in next step without further purification. Brown solid (55 mg, 95%). MS (ESI): m/z=216.2 [M+H]+.
