Embodiment 1
[0044] Synthesis of N-((17β)-3-hydroxyl-1,3,5(10)-estratrien-17-yl)-o-methoxybenzamide:
[0045] Take 150 mg of the second compound 2, dissolve it in 10 mL of dichloromethane, add 1 mL of triethylamine, slowly add 90 μL of o-methoxybenzoyl chloride, follow the reaction by TLC, react at room temperature for 3 h, spin dry under reduced pressure, and extract with ethyl acetate three times , washed 2 times with water, washed 1 time with saturated brine, dried over anhydrous sodium sulfate, spin-dried, separated by column chromatography (eluent is V 二氯甲烷 :V 甲醇 =100:1), a white solid was obtained with a yield of 20%, m.p.235~236°C, and the structure of the product was determined to be N-((17β)-3-hydroxyl-1,3,5(10 )-estratrien-17-yl)-o-methoxybenzamide, its chemical structure is as shown in the following formula:
[0046]
[0047] Among them, R=R 1 =
Embodiment 2
[0049] Synthesis of N-((17β)-3-hydroxyl-1,3,5(10)-estratrien-17-yl)-p-toluamide:
[0050] Take 2150 mg of the second compound, dissolve it in 10 mL of dichloromethane, add 1 mL of triethylamine, slowly add 66 μL of p-toluoyl chloride, follow the reaction by TLC, react at room temperature for 3 h, spin dry under reduced pressure, extract with ethyl acetate three times, wash with water 2 times, washed 1 time with saturated brine, dried over anhydrous sodium sulfate, spin-dried, and separated by column chromatography (eluent was V 二氯甲烷 :V 甲醇 =100:1), a white solid was obtained with a yield of 20%, m.p.139~141° C., and the structure of the product was determined to be N-((17β)-3-hydroxyl-1,3,5(10 )-estratrien-17-yl)-p-toluamide, its chemical structure is as shown in the following formula:
[0051]
[0052] Among them, R=R 2 =
Embodiment 3
[0054] Synthesis of N-((17β)-3-hydroxy-1,3,5(10)-estratrien-17-yl)-3-phenyl-propionamide:
[0055] Take 150 mg of the second compound 2, dissolve it in 10 mL of dichloromethane, add 1 mL of triethylamine, slowly add 74 uL of 3-phenylpropionyl chloride, follow the reaction by TLC, react at room temperature for 3 h, spin dry under reduced pressure, and extract with ethyl acetate three times. Wash twice with water and once with saturated saline. Dry over anhydrous sodium sulfate, spin dry, and separate by column chromatography (eluent is V 二氯甲烷 :V 甲醇 =100:1), a white solid was obtained. m.p.179-181°C, the structure of the product was determined to be N-((17β)-3-hydroxyl-1,3,5(10)-estratrien-17-yl)-3-benzene by IR, NMR and MS analysis Base-propionamide, its chemical structure is as shown in the following formula:
[0056]
[0057] Among them, R=R 3 =
