Reaction Steps

3.0 g (0.01 mol) of 3-hydroxy-(4-hydroxyphenyl)pyrrolidine·benzoate are dissolved in 100 ml of water. The solution is then brought to pH 1 with concentrated hydrochloric acid. The benzoic acid precipitated is extracted with ether and the clear aqueous solution evaporated. The solid residue is recrystallized from ethanol. There is obtained 3-(4-hydroxyphenyl)-3-pyrroline·HCl in the form of light beige crystals, mp 222° C. (from ethanol).
