1.7 g (4.8 mmol) of dimethyl 4-[3-(3-ethyl-4-hydroxyphenyl)propyl]phthalate (Example 1f are dissolved in 50 ml of ethyl ether, and this solution is slowly added to a suspension of 435 mg (11.4 mmol) of lithium aluminum hydride. The medium is stirred for 30 minutes and is then sequentially treated with 450 μl of water, 450 μl of 15% sodium hydroxide and 1.5 ml of water. The reaction medium is poured into a 1N hydrochloric acid solution, and extracted with ethyl ether. A white solid is obtained (m=1.2 g, m.p.=82° C., y=84%).
