Participants

Reaction Steps

As in Example 19, (E)-4-[3-[3-(4-fluorophenyl)-1-(1-methylethyl)-1H-indol-2-yl]-2-propenyloxy]-alpha-oxobenzeneacetic acid methyl ester (0.354 g) in methanol (5 mL) was treated with 1N sodium hydroxide (0.9 mL). The usual work up gave 0.4 g of a oil, which was dissolved in diethyl ether and morpholine (0.07 g) was added. Crystallization was induced and the recovered solid was recrystallized from dichloromethane-ethyl acetate to provide 0.26 g of (E)-4-[3-[3-(4-fluorophenyl)-1-(1-methylethyl)-1H-indole-2-yl]-2-propenyloxy]-alpha-oxobenzeneacetic acid (1:1) morpholine salt as a colorless solid, mp 151°-152° C.
