[0005] Chinese patent CN103772433A and CN200510021054 adopt 2-adamantanone and substituent-protected dimethyl / ethyl carbomethoxybenzyl methyl ether as raw material to obtain intermediate through Wittig reaction. This route also requires lower operating temperature (- 70 to -50 degrees), is also not conducive to industrial production
[0006] Chinese patent (CN103951704A) uses adamantane-2-aldehyde and 3-hydroxyl-protected phenyl Grignard reagents as raw materials to synthesize key intermediates. The synthetic route used is relatively long, and it is also not easy for industrial application.
U.S. Patents US4956477, US6417380 and US6124478, use cyano-substituted adamantane to prepare key intermediates through Grignard reaction, and use highly toxic cyanide in the process, making this process route also unsuitable for industrial production
