[0046] In order to achieve the above object, the present invention also provides a preparation method for the 7-azaspiro[5.6]dodecan-10-one compound, which specifically includes the following steps.
[0047] Step 1. Add 1 times the amount (molar amount) of bromobenzene and 0.5 times the amount of magnesium strips into the reaction bottle, dissolve them in an appropriate amount of ether, initiate at 35°C, and monitor the reaction progress by thin-layer chromatography. After the reaction was completed, 1.1 times the amount of cyclohexanone was added, and the reaction was carried out at 35° C. for 5 hours. After the reaction was completed, the reaction solution was added to aqueous ammonium chloride solution, extracted with ether, and the extract was dried and evaporated under reduced pressure to obtain 1-phenylcyclohexanol.
[0048] Step 2. Add 1-fold amount of 1-phenylcyclohexanol to the reaction flask, appropriate amount of dichloromethane as solvent, 2-fold amount of sodium a...

[0058] Preparation of 3,4-dihydrospiro[benzo[c]azepine-1,1'-cyclohexane]-5(2H)-one (A1).
[0059] a. Preparation of 1-phenylcyclohexanol.
[0060] Add bromobenzene (50g, 0.31mol) and magnesium strips (8.13g, 0.33mol) into a 1000mL three-necked flask, dissolve them in an appropriate amount of ether, and initiate at 35°C. After the reaction was completed, cyclohexanone (34.38 g, 0.35 mol) was added and reacted at 35° C. for 5 hours, and the reaction progress was monitored by thin-layer chromatography. After the reaction was completed, the reaction liquid was added into a saturated aqueous ammonium chloride solution, extracted with ether, the extract was dried, and evaporated under reduced pressure to obtain the product with a yield of 95.5%.
[0061] b. Preparation of 1-azido-1-phenylcyclohexane.
[0062] Add 1-phenylcyclohexanol (20.00g, 0.11mol), 500mL of dichloromethane, sodium azide (8.11g, 0.12mol), trifluoroacetic acid (25.88g, 0.23mol) into a 1000mL reaction flask, at r...

[0075] The preparation of 3,4-dihydrospiro[benzo[c]azepine-1,1'-cyclohexane]-5(2H)-one is as in Example 1.
[0076] a. 2-(Propyl-2-yn-1-yl)-3,4-dihydrospiro[benzo[c]azepine-1,1'-
[0077] Preparation of cyclohexane]-5(2H)-one.
[0078]Add 3,4-dihydrospiro[benzo[c]azepine-1,1'-cyclohexane]-5(2H)-one (1.00g, 0.004mol) and 50mL of acetonitrile into a 100mL reaction flask, Potassium carbonate (1.21 g, 0.009 mol), propyne bromide (0.57 g, 0.005 mol), heated to reflux at 85°C, and the reaction progress was monitored by thin-layer chromatography. After the reaction is complete, filter with suction, add an appropriate amount of water to the filtrate for extraction, dry the extract and evaporate under reduced pressure to obtain 2-(propyl-2-yn-1-yl)-3,4-dihydrospiro[benzo [c] Aza-1,1'-cyclohexane]-5(2H)-one.
