Embodiment 1

[0463] N-(4-([1,2,4]triazol[4,3-c]pyrimidin-7-yloxy)-3-methylphenyl)-5-(3-(dimethylamino) Azetidin-1-yl)-6-methoxyquinazolin-4-amine

[0464]

[0465] Step 1: 4-Chloro-6-hydrazinopyrimidine

[0466]

[0467] To a solution of 4,6-dichloropyrimidine (100 g, 675.7 mmol) in EtOH (900 mL) was added 50 wt% aqueous hydrazine (130 mL) dropwise at 45°C over 2 hours. The reaction was then stirred at 45-50°C for 2 hours. The crude mixture was filtered and the solid was washed with water to give the desired product (91 g, 94%) as a yellow solid. MS(ESI)m / z:145.1(M+H) + .

[0468] Step 2: 7-Chloro-[1,2,4]triazolo[1,5-c]pyrimidine

[0469]

[0470] 4-Chloro-6-hydrazinopyrimidine (91 g, 632 mmol) was dissolved in HC (OMe) 3 The solution in was stirred overnight at 90 °C. The crude mixture was concentrated and washed with NaHCO 3 Dilute with aqueous solution (500 mL). The resulting mixture was extracted with EtOAc (500 mL×2). The organic phase was washed with water and brin...

Abstract

The present application relates to novel quinazoline compounds as inhibitors of type I receptor tyrosine kinases, the pharmaceutical compositions comprising one or more of the compounds and salts thereof as an active ingredient, and the use of the compounds and salts thereof in the treatment of hyperproliferative diseases, such as cancer and inflammation, in mammals and especially in humans.

Description

technical field [0001] The application relates to novel quinazoline compounds as type I receptor tyrosine kinase inhibitors, pharmaceutical compositions comprising one or more of the compounds and their salts as active ingredients, and the compounds and their salts in mammals, especially are uses in the treatment of hyperproliferative diseases such as cancer and inflammation in humans. Background technique [0002] The type I tyrosine kinase receptor family consists of four structurally related receptors: EGFR (ErbB1 or HER1), ErbB2 (HER2), ErbB3 (HER3) and ErbB4 (HER4) (Riese and Stern, Bioessays (1998) 20 :41-48; reviewed in Olayioye et al., EMBO Journal (2000) 19:3159-3167; and Schlessinger, Cell (2002) 110:669-672). All four family members have a nearly identical structure consisting of an extracellular region or extracellular domain or ligand-binding domain, a single transmembrane domain, and an intracellular cytoplasmic tyrosine kinase domain. [0003] HER2 has been ...
