[0429] where A 1 、A 2 、A 3 、A 4 、A 5 、A 6 、A 7 、A8 、A 9 , R 5 has the above meaning.

[0430] Compound X1. In a round bottom flask equipped with a stirrer, thermometer and reflux condenser, mix in the indicated order: 200 mL of DMF, 0.1 mol of the corresponding dihalogenated benzene X1-2, 0.1 mol of the corresponding hydroxypyridine X1-1 and 0.2 mol of cesium carbonate or potassium carbonate. The mixture was stirred at 100° C. for 2-6 hours under inert gas; TLC method was used to ensure completion of the reaction. Then, most of the solvent was distilled off using a rotary evaporator; 200 mL of ethyl acetate was added, and the resulting suspension was filtered through celite. The filtrate was evaporated. The resulting product was purified by column chromatography, eluent: ethyl acetate:methanol (9:1). The product obtained is the compound of formula X1 in 60% to 80% yield.

Description

technical field [0001] The present invention relates to novel inhibitors of Bruton's tyrosine kinase, their preparation, pharmaceutical compositions comprising such compounds and the use of such compounds or such compositions as medicaments for the treatment of diseases and disorders. Background technique [0002] Bruton's tyrosine kinase (Btk), a member of the Tec family of non-receptor tyrosine kinases, is a key signaling enzyme expressed in all hematopoietic cell types except T lymphocytes and natural killer cells. Btk plays a crucial role in B cell signaling pathways linking cell surface B cell receptor (BCR) stimulation with downstream intracellular responses. [0003] Btk is a key regulator of B cell development, activation, signaling and survival (Kurosaki, Curr. Op. Imm., 2000, 276-281; ​​Schaeffer and Schwartzberg, Curr. Op. Imm. 2000, 282-288). In addition, Btk plays a role in numerous other hematopoietic cell signaling pathways, for example, Toll-like receptor (T...
