Example Embodiment

[0042] Example 1

[0043]Under nitrogen protection, add magnesium chips (2.64g, 0.11mol), 0.05g iodine, 100ml anhydrous tetrahydrofuran to a 500ml four-necked flask equipped with a mechanical stirrer, a reflux condenser, a constant pressure dropping funnel, and a thermometer, and heat to 60 degrees, add bromobenzene (15.7g, 0.1mol) dropwise, keep the solvent in a slightly boiling state, and obtain 0.1mol of bromobenzene Grignard reagent. Then continue to add dropwise 150ml tetrahydrofuran solution of 1-bromoadamantane (32.25g, 0.15mol), add anhydrous ferrous chloride (0.635g, 0.005mol), keep the temperature at 60 degrees and react for 24 hours, such as image 3 Shown is a schematic diagram of the reaction mechanism of ferrous chloride as a catalyst. TLC monitors the end of the reaction, cools to room temperature, adds a saturated aqueous ammonium chloride solution to quench the reaction, extracts the organic phase with ethyl acetate, and washes the organic phase with a saturat...

Abstract

The invention relates to a preparation method of 1-phenyl adamantane and the obtained 1-phenyl adamantane, and belongs to the technical field of drug synthesis. The preparation method comprises the following steps: taking 1-bromoadamantane and bromobenzene as raw materials, preparing the bromobenzene into a bromobenzene Grignard reagent in an organic solvent, and carrying out a coupling reaction with the 1-bromoadamantane under the catalysis of Lewis acid so as to obtain the target product 1-phenyl adamantane with high yield, and the Lewis acid is a metal chloride. The method is simple in synthesis process, easy to operate and suitable for industrial large-scale production.
