Reaction Steps
50 gm (0.23 mol) of 1-(2'-fluoro-4-biphenylyl)-1-hydroxy-ethane, m.p. 88° C., (prepared from 2'-fluoro-4-biphenylyl-methyl-ketone by reduction with sodium borohydride in methanol) were dissolved in 500 ml of benzene, 32.2 gm (0.276 mol) of 80% mercapto-acetic acid and 1 gm of p-toluenesulfonic acid were added, and the mixture was heated at its boiling point for 1 hour, using an apparatus equipped with a water trap. 20.5 ml of water were separated. The benzene solution was washed with water after cooling, dried and evaporated. The crystalline residue was recrystallized from benzene/cyclohexane (2:1), whereby 38.0 gm (61.5% of theory) of the title compound, m.p. 125°-127° C., were obtained.
