Procedure
1.6 g (53 mmol) of sodium hydride (80% in oil) and 50 mi of THF are introduced into a round-bottomed flask and a solution of 15 g (49 mmol) of the phenol obtained above in (a), dissolved in 100 mi of DMF, is added dropwise. The mixture is stirred until gaseous evolution has ceased and 3.1 ml (49 mmol) of methyl iodide are then introduced. The mixture is stirred at room temperature for four hours, the reaction medium is poured into water and the organic phase is separated after settling has taken place, then dried over magnesium sulphate and evaporated. The residue obtained is ground in the minimum amount of hexane and filtered off. 12.6 g (80%) of 2-(1-adamantyl)-5-bromoanisole, melting point 159°-160° C., are collected.
