A method for preparation of 6-[3-(1-adamantyl)-4-methoxyphenyl]-2-naphthoic acid is disclosed based on “one pot” synthesis approach including a direct synthesis of boronic acid derivative from 2-(1-adamantyl)-4-bromoanisole and cycloboranes with a subsequent Suzuki-Miyaura coupling with 6-halonaphthenoates and basic hydrolysis of the reaction product in ethylene glycol or 1,2-propanediol.

A process for preparation of 6-[3-(1-adamantyl)-4-methoxyphenyl]-2-naphthoic acid from 2-(1-adamantyl)-4-bromanisolee is disclosed, based on transformation of 2-(1-adamantyl)-4-bromanisole into a Grignard's reagent by using metallic magnesium, anhydrous lithium chloride and dibromoethane followed by transmetallation with borates to 3-(adamantyl)-4-methoxyphenylboronic acid, which is converted into 6-[3-(1-adamantyl)-4-methoxyphenyl]-2-naphthoic acid esters by Suzuki-Miyaura cross-coupling reaction with alkyl-6-halonaftoates catalyzed by Pd [0] or Pd/phosphine ligands and followed by basic hydrolysis in ethylene glycol or 1,2-propanediol of ester thus obtained into 6-[3-(1-adamantyl)-4-methoxyphenyl]-2-naphthoic acid.
