Embodiment 1

[0025] The synthesis of embodiment 1 compound I-1

[0026]

[0027] Step 1. Synthesis of compound IV-1

[0028] Compound II-1 (2.50g, 10mmol), Compound III (2.06g, 10mmol), Pd(OAc) 2 (0.22g, 1mmol), BINAP (2,2'-bisdiphenylphosphino-1,1'-binaphthyl, 0.62g, 1mmol) and t-BuOK (2.24g, 20mmol) were added to 50mL dry 1 , 2-dimethoxyethane (DME), the reaction mixture was stirred overnight under nitrogen atmosphere, TLC detection found that the reaction was complete.

[0029] The reaction mixture was carefully poured into 200mL ice water, stirred, and washed with 50mL×3CH 2 Cl 2 After extraction, the extract phases were combined, washed successively with 1% dilute hydrochloric acid and brine, and dried over anhydrous sodium sulfate. The desiccant was removed by suction filtration, the filtrate was evaporated to dryness on a rotary evaporator, and the residue was purified by silica gel column chromatography to obtain compound IV-1, ESI-MS, m / z=376 ([M+H] + ).

Abstract

The invention relates to the field of SSAO inhibitors, in particular to a triazole structural compound containing piperazine and piperazine, a preparing method thereof, and application thereof in preparing medicine for treating inflammatory diseases, immune diseases and tumors, wherein R is an alkyl group containing C1-C5.

Description

technical field [0001] The present invention relates to the field of SSAO inhibitors. Specifically, the present invention relates to a class of piperazinyl- and piperazine-triazole-containing compounds that have a therapeutic effect on inhibiting SSAO, their preparation methods, and their use in pharmacy. Background technique [0002] Semicarbazide-sensitive amine oxidase (SSAO) activity is produced by vascular adhesion protein-1 (Vascular Adhesinon Protein-1, VAP-1) or copper-containing amine oxidase (AmoneOxidase, Copper Containing 3, AOC3 ), which belongs to the family of copper-containing amine oxidases (EC.1.4.3.6). Therefore, inhibitors of SSAO enzymes can also regulate the biological functions of VAP-1 protein. Members of this enzyme family are sensitive to inhibition by semicarbazides and use copper ions and the protein-derived hydroxydopaquinine (TPQ) cofactor for the oxidation of primary amines to aldehydes, hydrogen peroxide, and ammonia Deamination.
