Yield	Reaction Conditions	Operation in experiment
7.6 g	Stage #1: 1-methyl-1,2,3,5,6,7-hexahydroazepin-4-one; benzoic acid hydrazide With potassium hydroxide In water at 25 - 35℃; for 1h; Stage #2: With sodium tetrahydroborate In water at 0 - 10℃; for 2h;	1.1-6.1 1) Put 1.7g of potassium hydroxide and 50mL of drinking water into the reaction flask at room temperature, stir until it is clear,Then add 3.9g 1-methylhexahydroazepine-4-one and 4.2g benzoyl hydrazide,React at 2535 for 1h, after the reaction is complete, cool down to 010,Add 3g sodium borohydride in batches. After the addition is completed, the reaction is kept at 010 for 2h, and the reaction is complete.Add hydrochloric acid to quench the excess sodium borohydride,Then add 50% potassium carbonate solution to adjust pH=1011, add 50mL dichloromethane,Separate the liquids to take the organic phase, and then extract the aqueous phase with 50 mL of dichloromethane once, combine the organic phases,Wash twice with 50mL*2 drinking water, and then wash once with 50mL saturated sodium chloride solution,The organic phase was dried with anhydrous sodium sulfate, filtered with suction, and the filtrate was concentrated to dryness under reduced pressure.7.6 g of compound 1 was obtained as a brown oil.
