As in Example 227, (E)-3-[3-(4-fluorophenyl)-1-(1-methylethyl)-1H-indol-2-yl]-2-propenoic acid methyl ester (4.43 g) in dry dichloromethane (60 mL) was treated with diisobutylaluminum hydride in toluene (1.5M; 30 mL) at -65° C. for 1 hour, then was worked up as previously described to give 4.15 g of (E)-3-[3-(4-fluorophenyl)-1-(1-methylethyl)-1H-indol-2-yl]-2-propen-1-ol as a yellow oil. A portion (0.2 g) was purified by chromatography over silica gel (diethyl ether-hexane; 1:19) to furnish 0.175 g of the analytically pure alcohol as an oil.
