실험 절차
To a stirred solution of 2-(methyloxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinamine (3 g, 12.00 mmol) in pyridine (12 ml), 2,4-difluorobenzenesulfonyl chloride (1.774 ml, 13.19 mmol) was added and the reaction mixture stirred at RT for 2 h. 2 N hydrogen chloride (aq) (20 ml) and dichloromethane (20 ml) were added and the layers separated. The aqueous layer was washed with additional dichloromethane (2×15 ml) and the organic layers combined, dried (hydrophobic frit) and evaporated in vacuo to give a brown oil. There was still some pyridine in the reaction mixture so 2M hydrogen chloride (aq) and dichloromethane (15 ml) were added to extract one more time. The solvent was removed in vacuo to give the title compound as an orange solid (4.3 g).
