Participants

Reaction Steps

0.390 G. of 4'-cyano-4-hydroxy-biphenyl are dissolved in 4.0 ml. of absolute pyridine and reacted with 0.323 g. of caproic acid chloride as in Example 1. The 0.613 g. of yellowish crystals obtained according to the procedure described in Example 1 are dissolved in benzene and chromatographed on 40 g. of silica gel. Benzene elutes 0.555 g. of colorless crystals which are recrystallized from acetone-hexane up to constant melting point and clearing point. The pure 4'-cyano-4-biphenylyl hexanoate obtained melts at 56.1° and has a clearing point of 70.7°. UV (EtOH): ε273 = 26,400.
