Embodiment 1
[0072] Synthesis of 3-cyclohexyl-3-(4-nitroanilino)-1-(4-methylphenyl)-1-propanone
[0073] Specific preparation method: dissolve 1 mmol of 4-nitroaniline in 1 to 3 ml of absolute ethanol, add 1 mmol of cyclohexanal and 1 mmol of 4-methylacetophenone, stir and dissolve at room temperature, and add 20 to 100 μL (catalytic amount) of concentrated hydrochloric acid or saturated ethanol solution of hydrochloric acid, precipitation occurs, stir at 0°C to 55°C for 8 to 48 hours, place in the refrigerator overnight, filter with suction, wash the solid with a small amount of ethanol to obtain a crude product. Pure product can be obtained by recrystallization with ethanol or acetone. The yield is 50%~99%.

Embodiment 2
[0076] Synthesis of 3-cyclohexyl-3-(4-nitroanilino)-1-(4-bromophenyl)-1-propanone
[0077] Specific preparation method: prepare according to the same method as in Example 1 except that 4-bromoacetophenone is used instead of 4-methylacetophenone.
[0078] 1 HNMR (DMSO-d 6 , 400MHz): δ7.95 (2H, d, J=8.7), 7.90 (2H, d, J=8.7), 7.73 (2H, d, J=8.3), 6.64 (2H, d, J=9.1), 4.02 (1H, q, J=11.7, 5.9), 3.26 (2H, d, J=6.3), 1.56~1.79 (6H, m), 1.03~1.20 (5H, m); yellow solid, melting point: 161~ 162°C (159°C).
