Patent ID: 8124770

Claim:
A synthesis procedure for a amino-substituted benzazolo[3,2-a]quinolinium chloride salts compound consisting of wherein R1 is chloride and a amino group, R2 is selected from a group consisting of methyl or hydrogen, and X is selected from a group consisting of sulfur and NR, wherein N is nitrogen and R a general alkyl group; comprising the steps of: a. synthesis of a nitro substituted 2-(2-chlorostyryl) benzazole; b. reduction of the nitro group to form an amino-substituted 2-(2-chlorostyryl) benzazole; and c. photo-induced cyclization procedure of said amino-substituted 2-(2-chlorostyryl) benzazole to generate a biological florescent amino-substituted benzazolo[3,2-a]quinolinium chloride salts, wherein said photo-induced cyclization procedure comprises selecting a vessel permeable to a wavelength of 350 nm and irradiations means, wherein said irradiation mean is equipped with 350 nm wavelength lamps.
