Abstract
NEW MATERIAL:compound shown by the formulaI(R is 1W8C alkyl or H).
USE: A liquid crystal compound useful as a display cell of liquid crystal. Exhibiting a high transition point of nematic isotropic liquid.
PROCESS: A compound shown by the formula II is reacted with a compound shown by the formula III in the presence of sulfuric acid and boric acid, to give a compound shown by the formula IV. This compound is reacted with a compound shown by the formula V(X is halogen) in an inert inorganic solvent, e.g., diethyl ether, etc., to give a compound shown by the formulaI. In order to remove a hydrogen halide liberated during the reaction out of the reaction system, a basic substance, e.g., pyridine, tertiary amine, etc. is preferably added to the inert solvent. The reaction is carried out from at normal pressureWa reflux temperature of the reaction mixture.
