2-(Methylthio)-5-pyrimidinecarboxylic acid ethyl ester - Introduction
Ethyl is an organic compound. Its chemical formula is C9H10N2O2S.
Nature:
Ethyl is a white crystalline solid. It has a melting point of 70-75 degrees Celsius and a density of 1.23g/cm3.
Use:
Ethyl As an organic synthesis intermediate, it has important applications in drug synthesis. It is often used in the synthesis of anti-tumor and anti-viral drugs, such as S-1 (Tegafur).
Preparation Method:
Ethyl can be prepared by ethanol esterification. The specific synthetic route may be as follows: firstly, 2-acetyl-4-methylthio-5-aminopyrimidine and bromoacetate are reacted under alkaline conditions to generate 2-acetyl-4-methylthio-5-bromopyrimidine, and then the target product is finally obtained through reduction, hydrolysis and esterification reactions.
Safety Information:
Ethyl is an organic compound. Care should be taken to avoid contact with skin and eyes during operation to prevent inhalation of its dust. If inhaled or exposed, rinse immediately with water and seek medical help. In addition, operate in a well-ventilated place to avoid fire and high temperature environment.
