Reaction Conditions:

with trifluoroacetic acid for 20 h;Reflux;

Steps:

A.7 7. Synthesis of 4,4’-((1s,3s,5r,7r)-adamantane-1,3-diyl)diphenol (7)

Phenol (47 g, 0.5 mol, dissolved in 920 ml_ TFA) was treated with 1 ,3- adamantanediol (40 g, 0.24 mol) and heated at reflux for 20 h. The reaction mixture was cooled to room temperature and quenched cautiously with H2O (1 L). A white solid precipitated, which was suspended in DCM and stirred overnight at 35 °C. The solid was filtered off, washed with DCM and dried under vacuum to yield 58 g (76 %) of white crystalline solid.
