Nitrocyclohexane and benzylbromide are subjected to condensation reaction in the presence of sodium hydride to obtain 1-benzyl-1-nitrocyclohexane. The product is reduced with lithium aluminum hydride to obtain 1-benzyl-1-aminocyclohexane. The product is reacted with methyl chloroformate to obtain 1-benzyl-1-methoxycarbonylaminocyclohexane, and the product is subjected to intramolecular cyclization in the presence of phosphorous oxychloride to obtain spiro[1,2,3,4-tetrahydroisoquinoline-2,1'-cyclohexan]-1-one.
