Reaktionsschritte

110 ml of a solution of methyl magnesium bromide (3.0 M) in diethyl ether was diluted with 100 ml of anhydrous tetrahydrofuran (THF). Then, the solution was put into a 1 liter flask and then maintained at 0° C. 2-adamantanone (45 g, 0.3 mol) was dropped slowly using a dropping funnel and then the reaction was stirred at room temperature for about 12 hours. After completion of the reaction, excess THF was removed using a rotary evaporator and then the resultant product was poured into water. Then, the resultant product was neutralized with dilute sulfuric acid and extracted using diethyl ether and was then dried over magnesium sulfate. The obtained crude product was recrystallized using n-hexane and a methylene chloride cosolvent to yield the desired product 2-methyl-2-adamantanol (yield: 80%).
