실험 절차

To a solution of 3-iodo-pyridin-2,6-diamine (3.3 g, 7.74 mmol, purity: 70%) described in Manufacturing Example 13-1-1 in toluene (50 mL) were added ethanol (25 mL), 2 N aqueous sodium carbonate solution (12.5 mL), 4-(4,4,5,5-tetramethyl-(1,3,2)dioxaborolan-2-yl)-1-trityl-1H-pyrazole (3.3 g, 7.56 mmol) described in Manufacturing Example 32-1-2 and tetrakis(triphenylphosphine)palladium (0) (1.02 g, 0.88 mmol) under nitrogen atmosphere, which was stirred for 2.5 hours at 95° C. Water and ethyl acetate were added to the reaction mixture at room temperature, which was then filtered through a Celite pad, and the filtrate was partitioned into water and ethyl acetate. The organic layer was washed with water and saturated aqueous sodium chloride, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under a reduced pressure. The residue was purified by NH silica gel column chromatography (ethyl acetate:heptane=1:2 then 2:1 then 5:1) to obtain the title compound (2.4 g, 73%).
