実験手順

A suspension of 5-[2-(4-benzyloxy-2-fluoro-phenyl)-1H-imidazol-4-yl]-1-isopropyl-1H-[1,2,4]triazole (84 g, 0.22 mol) and [1,3]dioxolan-2-one (48 g, 0.55 mol) in toluene (100 mL) was heated at 130° C. for 7.5 h allowing some solvent to evaporate until reaction was initiated. The cooled reaction mixture was concentrated in vacuo and the residue treated with acetonitrile (50 mL), stirred, sonicated and cooled in an ice bath. The resultant solid was collected by filtration, washed with cold acetonitrile then diethyl ether and dried in vacuo at 60° C. to give 2-[2-(4-Benzyloxy-2-fluoro-phenyl)-4-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-imidazol-1-yl]-ethanol (65.2 g, 70%). 1H NMR (400 MHz, CDCl3): 8.04 (1H, s), 7.80 (1H, d, J=0.71 Hz), 7.43-7.41 (6H, m), 6.89 (1H, dd, J=8.59, 2.50 Hz), 6.79 (1H, dd, J=11.73, 2.47 Hz), 5.93-5.92 (1H, m), 5.11 (2H, s), 4.02 (2H, t, J=4.93 Hz), 3.89 (2H, t, J=4.96 Hz), 1.49 (6H, d, J=6.61 Hz). LCMS: RT=3.30 min, [M+H]+=422.
