Embodiment 1

[0081] Preparation of 2-(morpholinyl-4-carbonyl)imidazo[1,2-a]quinoxalin-4(5H)-one

[0082]

[0083] first step:

[0084] Compound 1a (16.1g, 100mmol), 1b (19.5g, 100mmol) was dissolved in ethanol (200ml), heated to reflux, stirred and reacted for 8 hours, TLC detected the reaction, concentrated under reduced pressure after the reaction was completed, and separated by column chromatography to obtain Off-white solid 20.3g, yield 79.0%.

[0085] Step two:

[0086] Compound 1c (20.0g, 77.7mmol) obtained in the first step was dissolved in a mixed solvent of ethanol (100ml) and water (100ml), and sodium hydroxide (6.2g, 155.5mmol) was added at room temperature, and the reaction was stirred at 40°C 6 Hours, TLC detection reaction, after the completion of the reaction, ethanol was removed under reduced pressure, the remaining solution was poured into stirred dilute hydrochloric acid, the solid was precipitated, filtered, the filter cake was washed with water, and dried to obtain...

Moreover, synthesis steps of the compounds are simple, so that the compounds have higher economic utilization value.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and specifically relates to a class of compounds with toll-like receptor regulating effects, pharmaceutical compositions, preparation methods and uses thereof. Background technique [0002] Toll-like receptors (Toll-like receptors, TLR) are an important class of protein molecules involved in nonspecific immunity (innate immunity), and are also a bridge connecting nonspecific immunity and specific immunity. TLRs are single transmembrane non-catalytic proteins that recognize molecules with conserved structures derived from microorganisms. When microorganisms break through the body's physical barriers, such as skin, mucous membranes, etc., TLR can recognize them and activate the body to generate immune cell responses. Toll-like receptors are characterized by an extracellular leucine-rich domain and a major transmembrane protein with a cytoplasmic extension containing a conserved region. The inna...
