Procedure: Under the protection by nitrogen, ortho-methylphenylethanone (134 g, 1.0 mol) is dissolved in 1000 ml of tetrahydrofuran and then cooled to −5° C., into which 2M methylmagnesium chloride in tetrahydrofuran (550 ml) is slowly added dropwise at below 0° C. After the addition, the reactant solution is stirred at room temperature for 4 hours under the detection by TLC. When the reaction is complete, 200 ml of saturated NH4Cl solution is slowly added dropwise into the reactant solution and stirred until no bubbling from the solution. The reactant solution is then extracted by dichloromethane (500 ml×3), the extracts are combined, dried by anhydrous sodium sulfate, absorbed by activated carbon, filtered and then the solvent is distilled using rotary evaporator to obtain 124 g of 2-ortho-methylphenyl-2-propanol as a light yellow sticky liquid, with a yield of 82.6%. is slowly added dropwise at below 0° C After the addition stirred until no bubbling from the solution The reactant solution is then extracted by dichloromethane (500 ml×3) dried by anhydrous sodium sulfate absorbed by activated carbon filtered the solvent is distilled evaporator

After the addition, the reactant solution is stirred at room temperature for 3 hours under the detection of TLC. When the reaction is complete, 200 ml of saturated NH4Cl solution is slowly added dropwise into the reactant solution and stirred until no bubbling from the solution. The resulted solution is then extracted by dichloromethane (500 ml×3), the extracts are combined, dried by anhydrous sodium sulfate, absorbed by activated carbon, filtered, and then the solvent is distilled out using rotary evaporator to obtain 132 g of 2-ortho-methylphenyl-2-propanol as a light yellow sticky liquid, with a yield of 88%. is slowly added dropwise at below 0° C After the addition stirred until no bubbling from the solution The resulted solution is then extracted by dichloromethane (500 ml×3) dried by anhydrous sodium sulfate absorbed by activated carbon filtered the solvent is distilled out evaporator
