    • A dry THF solution (134mL) of p-bromophenol (9.7 g, 50 mmol) was added slowly under argon atmosphere at -78 °C to a hexane solution of n-BuLi (70.4 mL, 1.5 M, 0.100 mol, The mixture was warmed up to +5°C and stirred at that temperature for 1 h. To the mixture cooled to -50°C was added a dry THF solution of 2 (0.015 mol, 15 mL, The mixture was warmed up to +10°C and stirred for Ih. Then, the mixture was hydrolyzed by adding 5% HCl until obtaining a yellow solution. The resulting mixture was evaporated and the residue was dissolved in diethyl ether, washed with water, concentrated, dried, filtered, and evaporated to dryness. The residue was triturated with dry pentane for 20 min. The crude product obtained by decantation of pentane was chromatographed on silica gel with chloroform/ethyl acetate (1:1) as eluent to give 3 as semi-solid (3.15 g, 60, Mp 103-105°C; IR KBr, cm -1, 825, 1176, 1501, 1595, 3348. 29SiNMR
