[0088] (1) 60mg (0.299mmol) 2,4-dichloro-5-methylpyrrolo[2,3-d]pyrimidine, 77mg (0.358mmol) N-[3-(aminomethyl)pyridin-2-yl ]-N-methylmethanesulfonamide and 0.100mL (0.585mmol) of N,N-diisopropylethylamine were dissolved in 4mL of ethanol, and the external bath was refluxed and stirred. The reaction stopped after 40 h, and a large amount of solids were precipitated out in the reaction liquid at this time. The reaction solution was transferred to an ice bath and stirred for 30 min, and filtered to obtain 75 mg of a light yellow solid with a yield of 66.0%. 1 H-NMR(DMSO-d6,400MHz)δ=2.38(s,3H),3.12(s,3H),3.28(s,3H),4.70(s,2H),6.68(s,1H),7.38(m ,2H),7.85(d,J=6.36Hz,1H),8.40(d,J=2.96Hz,1H),11.43(s,1H)ppm.ESI-MS m / z381.1[M+H] + .

The reaction stopped after 16 hours, and a large amount of solids precipitated out in the reaction solution. The reaction solution was transferred to an ice bath and stirred for 30 min, and filtered to obtain 220 mg of a light yellow solid with a yield of 60.0%. m.p.>250℃. 1 H-NMR(DMSO-d6,400MHz)δ=3.12(s,3H),3.28(s,3H),4.79(d,J=5.24Hz,2H),7.40(dd,J=7.64Hz,J=4.54 Hz,1H),7.70(t,J=5.84Hz,1H),7.86(d,J=6.16Hz,1H),8.20(s,1H),8.43(d,J=2.92Hz,1H),12.92( s,1H)ppm.ESI-MS m / z392.1[M+H] + .

Abstract

The invention belongs to the field of organic chemistry and drug synthesis, and relates to pyrrolo[2,3-d]pyrimidine compounds and salts thereof. The compounds and salts thereof have a remarkable inhibiting effect on focal adhesion kinase, and can be used for preparing medicines for treating related diseases of the focal adhesion kinase, especially can be used for preparing medicines for treating related tumors with high expression of the focal adhesion kinase.

Description

technical field [0001] The invention belongs to the field of organic chemistry and drug synthesis, and relates to a class of pyrrolo[2,3-d]pyrimidine compounds and their salts. The compound and its salts have significant inhibitory effect on focal adhesion kinase and can be used to prepare and treat focal adhesions Medicines for kinase-related diseases, especially medicines for treating tumors related to high expression of focal adhesion kinases. Background technique [0002] The prior art discloses that focal adhesion kinase (FAK) is a non-receptor tyrosine kinase and plays a central role in integrin-mediated cell signaling pathways. Studies have shown that FAK has two conformations, active and inactive. Under the action of integrin, the conformation of FAK in the inactive state changes, causing autophosphorylation of tyrosine residue Y397, and FAK turns into an active state. FAK combines with Src family proteins to form a complex, which jointly activates downstream comple...
