실험 절차
To a solution of 3-trimethylsilanylethynyl-pyridin-2-ylamine (28.1 g, 148 mmoL) described in Manufacturing Example 1-2-2 in tetrahydrofuran (300 mL) was added tetrabutylammonium fluoride (1 M tetrahydrofuran solution, 20 mL, 20 mmol), which was stirred for 15 minutes at room temperature. Water was added to the reaction solution, which was then extracted with ethyl acetate 4 times. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under a reduced pressure. The residue was purified by silica gel chromatography (heptane:ethyl acetate=1:1 then 1:2) to obtain the title compound (16.4 g, 93.7%).
