Reaction Steps

(4'-Methoxy-4-biphenyl)-methyl-ketone [see W. S. Johnson et al, J. Amer. Chem. Soc. 68, 1648 (1946)] was reduced with sodium borohydride to 1-(4'-methoxy-4-biphenylyl)-ethanol (m.p. 120°-122° C, from cyclohexane), and the carbinol was converted into 1-(4'-methoxy-4-biphenylyl)-1-chloroethane, m.p. 122°-124° C (from cyclohexane), with hydrogen chloride. 5.2 gm of 1-(4'-methoxy-4-biphenylyl)-1-chloroethane (0.021 mol) were admixed in 21 ml of dry dimethyl sulfoxide with 2.7 gm (0.026 mol) of thioglycolic acid methyl ester and then with 3.5 gm (0.026 mol) of dry potassium carbonate. The mixture was stirred at room temperature for 45 minutes. The reaction product was precipitated with water, suction-filtered off, washed and dried. Yield: 6.8 gm (100% of theory); m.p. 59°-61° C. A sample recrystallized from cyclohexane, analized as follows:
