Versuchsvorschrift

To a 0° C. suspension of 4′-Hydroxy-2′-methylacetophenone (716 mg, 4.77 mmol), [2-(2,6-Dichloro-phenyl)-4-isopropyl-2H-pyrazol-3-yl]-methanol (1.36 g, 4.77 mmol), tri-n-butylphosphine (1.78 mL, 7.15 mmol) in toluene (20 mL) is added ADDP (1.80 g, 7.15 mmol). The reaction is warmed to room temperature and is stirred overnight. The reaction is concentrated under reduced pressure and the residue is chromatographed (0% to 30% EtOAc/Hex) to yield the title compound (857 mg, 64%). 1H NMR (400 MHz, CDCl3) δ 7.70 (s, 1H), 7.65 (d, 1H, J=8.8 Hz), 7.42-7.38 (m, 2H), 7.32-7.27 (m, 1H), 6.64-6.58 (m, 2H), 4.85 (s, 2H), 2.99 (sept, 1H, J=7.0 Hz), 2.50 (s, 3H), 2.49 (s, 3H), 1.30 (d, 6H, J=7.0 Hz).
