NEW MATERIAL:A compound shown by formula I (R is 4-14C straight-chain alkyl; asterisk R is optically active 4-10C alkyl containing CH3 as branch at first or second position counted from carbon linked to oxygen). EXAMPLE:(S)-5-n-Octyloxy-2-[4'-(2-methyloctyloxy)phenyl]pyrimidine. USE:A ferroelectric chiral smectic liquid crystal compound. PREPARATION:A compound shown by formula II is reacted with a compound shown by formula III (Y optically active alkyl replaced with CH3 at first or second position counted from carbon linked to X; X is reactive group such as halogen, sulfonic ester, etc.) in the presence of a base such as metallic Na, etc., in a solvent such as DMF, etc., to give a compound shown by formula I.
