[0196] 1,2,3-Triazole (3.45g, 50mmol), 2-iodo-5-methylbenzoic acid (5.24g, 20mmol), cesium carbonate (11.72g, 36mmol), trans-N,N' -Dimethyl-1,2-cyclohexanediamine (0.51g, 3.6mmol), cuprous iodide (0.38g, 2mmol), N,N-dimethylformamide (30mL) were added to 100mL single-mouth circle in turn In the bottom flask, the temperature was gradually raised to 100°C for 4 hours under the protection of nitrogen. The reaction was stopped, cooled, diluted with tap water and extracted with ethyl acetate (200 mL×2). The aqueous layer was acidified with concentrated hydrochloric acid (pH=1~2) and then extracted with ethyl acetate (200mL×2). The organic layers were combined, dried over anhydrous sodium sulfate, filtered, and the filtrate was evaporated to dryness under reduc...

Description

Invention field [0001] The invention belongs to the technical field of medicine, and specifically relates to a class of octahydropyrrolo[3,4-c]pyrrole derivatives, pharmaceutical compositions containing such compounds, and their use methods and uses. More specifically, the compounds and pharmaceutical compositions of the present invention can be used as orexin receptor antagonists to treat, prevent or alleviate orexin receptor-related diseases. Background of the invention [0002] Orexin (orexin) is also called hypothalamic secretion, orexin, which includes orexin A and orexin B (or hypothalamic secretin-1 and hypothalamic secretin-2), which is a secretion from the hypothalamus The main physiological functions of the neuropeptides are as follows: 1. Regulating food intake, orexin can significantly promote eating, with a dose-dependent response, and activates the neurons that regulate eating; 2. Participating in the regulation of energy metabolism, orexin can be significant Incre...
