Procedure
A mixture of 5-(4-methoxyphenyl)-2-(4-nonylphenyl)-pyrimidine (60 g), hydrobromic acid (240 g) and acetic acid (1 l ) was refluxed for 40 hours, followed by distilling off most part of the acetic acid, pouring the residue into 2N-NaOH aqueous solution and recrystallizing the deposited crystals from ethyl acetate to obtain 5-(4-hydroxyphenyl)-2-(4-nonylphenyl)pyrimidine (32.6 g). This product had a C-SA point of 98.4° C. and a SA-I point of 138.6° C.
