Description
Technical Field
The invention relates to the field of pharmaceutical chemistry, in particular to a method for industrially synthesizing a drug Bei Lisi for treating recurrent refractory peripheral T cell lymphoma.
Background
Belinostat (belinostat) is a histone deacetylase inhibitor (histone deacetylase inhibitors, HDACI). Overexpression or deregulation of Histone Deacetylase (HDAC) causes excessive deacetylation of histone, remodelling of chromatin into a configuration inhibiting transcription, causing a decrease in expression of the corresponding gene, resulting in generation of canceration, and thus inhibition of HDAC is considered as an anticancer drug target with development prospect. Belinostat is a small molecule hydroxamate type HDACI, originally developed by topotargete Inc., chemical name:Nhydroxy-3- (3-phenylaminosulfonylphenyl) acrylamide, which was approved by the FDA for marketing in 7 of 2014, is currently recognized as an important drug for the treatment of T-cell lymphoma in the International market, and is also known for mesothelioma, B-cell lymphoma,Soft tissue sarcoma, colorectal cancer, liver cancer and the like also have single or combined treatment effects and have huge market potential, so that the development of a new technology of belisi has important significance.
The compound is disclosed in International patent WO0230879 for the first time, wherein the synthetic route of the compound is as follows:
in the first step of sulfonation reaction of the reaction route, fuming sulfuric acid is used, and is easy to cause explosion when meeting water, organic matters and oxidizing agents, has strong corrosiveness, has great danger and serious potential safety hazard in storage, transportation and use, and can also pollute the environment; the method has long route and multiple steps, and the total yield is only 1.3%, so that the industrialized production is difficult to realize.
The synthesis route II is as follows: the content of documents Synthetic Communication, 2009,40(17) 2520-2524 reports a synthetic route, which uses m-nitrobenzaldehyde as starting material, firstly makes olefination reaction, then reduces nitro group to amino group under the action of stannous chloride, then makes diazotization, sulfonation, amidation and hydroxylation successively so as to obtain belinostat.
In comparison to the first synthetic route, this route does not use highly corrosive raw materials such as fuming sulfuric acid and thionyl chloride. However, this route uses diazotisation reactions with a great risk of explosion, uses SO with a great environmental pollution 2 The gas, therefore, has great production safety hidden trouble and pollution source, and is difficult to realize large-scale industrialized production.
In summary, it is currently difficult to realize large-scale industrial production on the synthesis route of belinostat, either because of the use of highly polluting and corrosive reagents, or because of the dangerous diazotization reaction in the process route, or because of the long route and low yield. Therefore, the development of a green, environment-friendly, highly operable and safe belinostat synthesis method has important significance.

EXAMPLE 7 preparation of belinostat
IV (500 mg, 1.6 mmol) is dissolved in 1 mol/L NaOH in methanol and heated to 40-50 oC The reaction was continued at this temperature for 2 hours, and after completion of the hydrolysis reaction, TLC was monitored, the reaction was stopped, and the pH was adjusted to 2.2 with 1 mol/L aqueous hydrochloric acid, whereby precipitate was formed. Cooling the system to 20-30 deg.f oC Then filtering, washing the filter residue with water for several times, and transferring into an oven for drying to finally obtain the crude intermediate acid 0.45-g.
Catalytic amounts of DBU (3.7 mg, 0.024 mmol) were dissolved in isopropyl acetate (4 mL), followed by the addition of the last step of intermediate acid (0.45 g, 1.5 mmol) and thionyl chloride (0.13 mL, 1.8 mmol/L), at 20-30 oC Stirring was carried out overnight. After no reaction starting material remained as monitored by TLC, the reaction was stopped.
Into a 25 mL round bottom flask was added water (5 mL), THF (4 mL), and hydroxylamine hydrochloride (2.1 g, 30.8 mmol) and the temperature was reduced to 0-10 oC Stirring is started, the acyl chloride reaction liquid is slowly added dropwise while stirring, then the temperature is raised to room temperature, and the reaction is continued until the completion. After stopping the reaction, the system is layered, the water phase is removed, the oil phase is decompressed and distilled to remove most of the solvent, isopropyl acetate (3 mL) is added into the water phase, the system is precipitated, heptane (5 mL) is added into the water phase, the water phase is kept stand for a period of time, the water phase is filtered, and the filter residue is washed by the heptane for a plurality of times, and is dried in an oven to obtain a crude product. The crude product was then taken up in a mixed solvent (EtOH: H 2 O=1:1) to give the final product belinostat (0.33 g, 1.0 mmol), light orange solid, melting point 172-173 o The total yield from IV-belinostat was 65%.
