Reaction Steps

A mixture of S 3'-bromo-4'-(1-methylheptyloxy)-4-biphenylcarboxylic acid (56.7 g), cuprous cyanide (16.3 g) and dimethylformamide (140 ml) was heated for 12 hours under reflux, followed by cooling the resulting material to room temperature, treating with 10 wt. % ethylenediamine aqueous solution (700 ml), acidifying with 6N hydrochloric acid, collecting the precipitates by filtration, washing with boiling water, dry-sucking and recrystallizing from acetic acid to obtain S 3'-cyano-4'-(1-methylheptyloxy)-4-biphenylcarboxylic acid (40.8 g) (C-S, 100.0° C., S-I, 138.7° C.).
