Hydrochloric Acid → N-{4-[(3-isopropyl-1H-indol-5-yl)oxy]-3,5-dimethyl-phenyl}glycine

Participants

Reaction Steps

56 mg of ethyl N-{4-[(3-isopropyl-1H-indol-5-yl)oxy]-3,5-dimethylphenyl}glycinate (Example 3) are stirred in 7 ml of dioxane with 1.5 ml of IN sodium hydroxide for 2 hours at room temperature. The mixture is poured onto water, rendered acidic using 1N hydrochloric acid, extracted with ethyl acetate, the extract is dried and the solvent is removed in vacuo. 51 mg of N-{4-[(3-isopropyl-1H-indol-5-yl)oxy]-3,5-dimethyl-phenyl}glycine are obtained 1H-NMR (300 MHz, CDCl3): δ=1.29, d, 6H; 2.10, s, 6H; 3.07, sept., 1H; 3.70, s, 2H; 6.41, s, 2H; 6.73, m, 1H; 6.91, m, 2H; 7.21, d, 1H; 7.77, s, broad, 1H.
