Problems solved by technology

But at present, there is no p-N-(3-chloro-4-(3-fluorobenzoyloxy)phenyl)-6-(3-(4-methyl-1,4azaphosphin-1-yl) )prop-1-ynyl)quinazolin-4-amine p-toluenesulfonate drug crystal form, making the basic research of the drug blank
And, N-(3-chloro-4-(3-fluorobenzyloxy)phenyl)-6-(3-(4-methyl-1,4azaphosphin-1-yl)propan-1 -alkynyl) quinazoline-4-amine p-toluenesulfonate still has certain deficiencies in drug metabolism, and the bioavailability is not high

Abstract

The invention relates to the field of compound preparation and particularly relates to a novel crystal form of N-(3-chloro-4-(3-fluorobenzyloxy)phenyl)-6-(3-(4-methyl-1,4-azaphosphine-1-yl)propyl-1-alkynyl)quinazoline-4-p-toluidine sulfonate as well as a preparation method and application of the novel crystal form. The novel crystal form of N-(3-chloro-4-(3-fluorobenzyloxy)phenyl)-6-(3-(4-methyl-1,4-azaphosphine-1-yl)propyl-1-alkynyl)quinazoline-4-p-toluidine sulfonate having a better treating effect for excessive proliferative diseases is further obtained through crystallizing a mixed solvent prepared by mixing water and methanol, ethanol, n-propanol, isopropanol, acetone, acetonitrile, tetrahydrofuran or dioxane according to different proportions, so that not only is the pharmaceutical activity of the phosphorus-containing substituted quinazoline derivative improved, but also the bioavailability of the phosphorus-containing substituted quinazoline derivative is increased, and the blank for researching a drug with the crystal form of the phosphorus-containing substituted quinazoline derivative is made up.

Description

technical field [0001] The invention relates to the technical field of crystal form compounds, in particular to a new crystal form of a phosphorus-containing substituted quinazoline derivative and a preparation method and application thereof. Background technique [0002] N-(3-Chloro-4-(3-fluorobenzyloxy)phenyl)-6-(3-(4-methyl-1,4azaphosphin-1-yl)prop-1-yne Base) quinazoline-4-amine p-toluenesulfonate, which is a phosphorus-substituted quinazoline derivative. Its structural formula is as follows. It is a drug for the treatment of hyperproliferative diseases developed by Newkin Pharmaceuticals. The compound It is a type I receptor protein kinase inhibitor, which can be used to treat diseases related to abnormal protein kinase activity in mammals, such as cancer and inflammation. [0003] [0004] Chinese patent CN102711472A discloses a phosphorus-containing quinazoline derivative and a method of use thereof, including N-(3-chloro-4-(3-fluorobenzyloxy)phenyl)-6-(3- (4-Met...
