[0160]

[0161] first step

[0162] Methyl 2-bromo-4-methoxybutyrate 1b

[0163] Add methyl 4-methoxybutyrate 1a (1.6g, 12.1mmol) into 50mL of tetrahydrofuran, cool down to -78°C with a dry ice-acetone bath, and slowly add lithium bistrimethylsilylamide (12.7mL, 12.7mmol), added, stirred and reacted for 1 hour, added trimethylchlorosilane (1.31g, 12.1mmol), continued to stir and reacted for 20 minutes, then added N-bromosuccinimide (2.15g, 12.1mmol) , and stirred for 2 hours. The dry ice-acetone bath was removed, the temperature of the reaction solution was naturally raised to room temperature, the reaction was quenched with saturated ammonium chloride solution, the reaction solution was extracted with ethyl acetate (50mL×3), the organic phases were combined, and the organic phases were respectively saturated with water (50mL). Washed ...

Abstract

The invention relates to epoxy-substituted oxopyridine derivatives and their preparation method and application in medicine and concretely, relates to epoxy-substituted oxopyridine derivatives shown in the general formula (I), their preparation method, a pharmaceutical composition containing the derivatives and a use of the derivatives as therapeutic agents and especially as blood coagulation factor XIa (called as FXIa for short) inhibitors and in preparation of drugs for treating diseases such as thromboembolism. The definition of each substituent in the general formula (I) is the same as thedefinition in the specification.

Description

technical field [0001] The present invention relates to a new class of epoxy-substituted oxopyridine derivatives, a preparation method thereof, a pharmaceutical composition containing the derivative and its use as a therapeutic agent, especially as an inhibitor of factor XIa (Faxtor XIa, FXIa for short). Inhibitor and its use in the preparation of medicines for treating and preventing diseases such as thromboembolism. Background technique [0002] Cardiovascular and cerebrovascular diseases such as cerebrovascular disease, cerebral infarction, myocardial infarction, coronary heart disease and arteriosclerosis claim the lives of nearly 12 million people every year in the world, accounting for nearly 1 / 4 of the total death toll in the world, becoming the number one enemy of human health. In China, more than 2.6 million people die from cardiovascular diseases every year, and 75% of the surviving patients are disabled, and more than 40% of them are seriously disabled. The throm...
