반응 단계
A solution of 4-bromo-2-hydroxybenzonitrile (1 g, 5.05 mmol), potassium cyclopropyltrifluoroborate (1.495 g, 10.10 mmol), K3PO4 (5.05 ml, 15.15 mmol) and PdCl2(Amphos)2 (0.358 g, 0.505 mmol) in toluene (25 mL) was allowed to stir at 100° C. under nitrogen overnight. The mixture was then cooled to room temperature, diluted with EtOAc/NH4Cl(aq), and filtered through a pad of Celite. The organic layer was seperated, dried over Na2SO4, filtered and concentrated. The residue was purified by FCC (0-50% EtOAc/heptane) to provide 4-cyclopropyl-2-hydroxybenzonitrile, 1H NMR (400 MHz, CH2Cl2) δ 12.17 (br. s., 1H), 7.23 (d, J=8.34 Hz, 1H), 6.51-6.58 (m, 2H), 1.82 (tt, J=5.02, 8.37 Hz, 1H), 0.94-1.00 (m, 2H), 0.68-0.73 (m, 2H).
