NOVEL OXAZOLOPYRIDINE BASED COMPOUNDS AND A PREPARATION METHOD OF THE SAME

摘要

PURPOSE: A novel oxazolopyridine compound and a method for preparing the same are provided to be used as a precursor compound for fluorescence expression marker. CONSTITUTION: An oxazolopyridine compound is denoted by chemical formula 1. In chemical formula 1, R1, R2, R3, and R4 are different or same hydrogen atoms, halogen atoms, or C1-C6 alkyl groups; and R5 is C1-C20 alkyl groups. The oxazolopyridine compound is a precursor compound for a fluorescence expression marker. A method for preparing oxazolopyridine compound comprises a step of reacting oxazolyl-based phenol compounds of chemical formula 2 with alkanoyl chloride of chemical formula 3 under the presence of a base.
