A chiral phenylether compound having the formula ##STR1## wherein X is a halogen atom; m is an integer from 3 to 5, n is an integer from 3 to 12 and * designates an asymmetric carbon is disclosed. The chiral phenylether compounds are useful to prepare chiral smectic phase pyrimidine phenylether liquid crystal compounds of the formula. ##STR2## The reaction is carried by reacting (I) with butylithium, dissolving in ether and reacting with a 1-bromoalkane to yield (IV). Compounds (IV) are particularly well suited to broaden the useful temperature range of ferroelectric liquid crystal materials.
