Embodiment 1
[0171] Example 1 Preparation of 12-N-trifluoromethoxybenzenesulfonyl matrine butyric acid morpholine amide hydrochloride (KCA-1)
[0172]
[0173] Step 1: Preparation of matrine butyric acid (MT-1)
[0174]
[0175] Put matrine (1g, 4mmol) into 20mL 5N NaOH aqueous solution, heat to reflux for 9h, after the reaction, cool to room temperature, a large amount of white solid precipitates, filter, and slowly put the filter cake into 6N HCl, and keep the pH< 5. Evaporate the solvent water to dryness, add methanol to fully dissolve the residue, filter to remove inorganic salts, and obtain a methanol solution of matrine butyric acid, which is directly used in the next reaction.
[0176] Step 2: Preparation of methyl matrine butyrate (MT-2) hydrochloride
[0177]
[0178] Heat the MT-1 methanol solution obtained in step 1 to reflux for 2 hours, and detect it by TLC. After the reaction, evaporate the solvent methanol to dryness, heat 10 mL of absolute ethanol, a large amount ...
Embodiment 2
[0187] Example 2 Preparation of 12-N-trifluoromethoxybenzenesulfonyl matrine butyric acid azetidine amide hydrochloride (KCA-3)
[0188]
[0189] With reference to the operation steps described in Example 1, MT-11-1 and azetidine were reacted under the reaction conditions described in Step 5 and corresponding post-treatments were performed to obtain the target product, a white solid (96.8mg, 45 %); Melting point: 97-99°C.
