実験手順

This compound is prepared by the method described in Example 1 for 4-(4-acetyl-8-hydroxytridecyl)benzoic acid except that in Step D an equivalent quantity of 1-chloro-4-acetoxy-8-methylnonane is substituted for 1-chloro-4-acetoxynonane. The intermediates and final product thus obtained are, Step D: ethyl 4-(4-acetyl-4-tert-butoxycarbonyl-8-acetoxy-12-methyltridecyl)benzoate; Step E: ethyl 4-(4-acetyl-8-acetoxy-12-methyltridecyl)benzoate; and Step F: 4-(4-Acetyl-8-hydroxy-12-methyltridecyl)benzoic acid.
