Abstract

NEW MATERIAL:A 4-alkylphenyl 4-(5-alkyl-2-pyrimidyl)benzoate of formula I (R and R' are 1W10C straight chain alkyl).
EXAMPLE: 4-Pentylphenyl 4-(5-propyl-2-pyrimidyl)benzoate.
USE: A nematic liquid crystal compound capable of exhibiting a wide liquid crystal temperature range, having a high clear point, and usable as a component in a liquid crystal composition having a wide liquid crystal temperature range.
PROCESS: 4-Ethoxycarbonylbenzamidine hydrochloride of formula II obtained from p-cyanobenzoic acid as a raw material is reacted with a compound of formula III obtained from diethyl malonate and an alkyl bromide, and the reaction mixture is then subjected to reaction in four stages to give a p-(5-alkyl-2-pyrimidyl)benzoic acid of formula IV, which is further reacted with a p-alkylphenol of formula V to afford the compound of formula I.
