5 g of 4'-n-octyloxy-4-hydroxybiphenyl, 1.5 g of potassium hydrooxide, and 100 g of 95% ethanol were heated under reflux, and a solution wherein 4.2 g of p-bromobenzyl bromide was dissolved in 100 ml of ethanol was added thereto to effect reaction for 2 hours. The reaction liquid was treated in the ordinary method to obtain 6.1 g of 4'-n-octyloxy-4-biphenylyl p-bromobenzyl ether after recrystallization from ethyl acetate. The obtained product showed the following phase transition temperatures:
