Pyridine → HCID 21404276, compound

Participants

Reaction Steps

0.390 G. of 4'-cyano-4-hydroxy-biphenyl are dissolved in 4.0 ml. of absolute pyridine and reacted with 0.289 g. of valeric acid chloride as in Example 1. The 0.590 g. of brownish colored turbid oil obtained according to the procedure described in Example 1 are dissolved in benzene and chromatographed on 40 g. of silica gel. Benzene elutes 0.518 g. of a colorless, turbid oil which crystallizes upon trituration. It is recrystallized from acetone-hexane up to constant melting point and clearing point. The pure 4'-cyano-4-biphenylyl valerate obtained melts at 36.5°-36.9° and has a clearing point of 61.7°. UV (EtOH): ε271 = 25,800.
