실험 절차
To a 0° C. solution of [2-(2,6-dichloro-phenyl)-4-isopropyl-2H-pyrazol-3-yl]-methanol (3.0 g, 10.6 mmol), 4-amino-3-methyl-phenol (2.0 g, 15.8 mmol), and tri-n-butylphosphine (3.2 g, 15.8 mmol) in toluene (30 mL) is added a solution of 1,1′-(Azodicarbonyl)-dipiperidine (4.0 g, 15.8 mmol) in toluene (40 mL). The reaction mixture is allowed to warm to room temperature and is stirred for 3.0 h. The reaction mixture is partitioned between EtOAc (50 mL) and water (60 mL). The organic layer is washed with brine (60 mL), dried (Na2SO4), filtered, and concentrated under reduced pressure to a residue. The residue is purified by flash chromatography (EtOAc/Hexane) to afford the title compound as a solid (2.3 g, 56%). LC-ES/MS m/e 390.0 (M+1).
