-
Paragraph 0066-0067, (2019/07/23)
The object of the present invention is to provide a method for preparing 4-(piperidin-4-yl)morpholine, which is easy to operate. The object can be solved by a method for preparing 4-(1-benzylpiperidin-4-yl)morpholine, characterized in that 5-fold molar or more of morpholine is added to 1-benzyl-4-piperidone, and the mixture is reacted with hydrogen under 1 MPa or less in the presence of platinum catalyst or palladium catalyst.
2-amino-4-substituted pyridine derivative as well as synthesis method and application thereof

Paragraph 0266-0269, (2019/08/06)
The invention discloses a 2-amino-4-substituted pyridine derivative as well as a synthesis method and an application thereof. The derivative with the structural formula is a compound with the structure or pharmacologically acceptable salt, hydrate, solvate, polymorphic substance, tautomer, stereoisomer, isotope derivative or prodrug of the compound. The 2-amino-4-substituted pyridine derivative has higher EGFR (epidermal growth factor receptor) inhibition activity, has higher inhibition activity for human epidermal cell carcinoma cells, glioblastoma cells and the like and can be used for preparing drugs for treating and/or preventing and/or delaying and/or assisting in treatment and/or treatment of diseases related with too high EGFR activity.
