·First-aid measures:
General adviceConsult a physician. Show this safety data sheet to the doctor in attendance.If inhaled If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician. In case of skin contact Wash off with soap and plenty of water. Consult a physician. In case of eye contact Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. If swallowed Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
·Fire-fighting measures:
Suitable extinguishing media Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Wear self-contained breathing apparatus for firefighting if necessary.
·Accidental release measures:
Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8. Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Pick up and arrange disposal. Sweep up and shovel. Keep in suitable, closed containers for disposal.

1-cyclopropyl-4-oxo-7-fluoro-8-methoxy -1,4-dihydro-quinoline-3-carboxylic acid synthesizing method
-
Paragraph 0023; 0098; 0099, (2017/01/26)
The invention discloses a synthesis method of 1-cyclopropyl-4-oxo-7-fluoro-8-methoxy-1,4-dihydroquinolyl-3-carboxylic acid. The synthesis method comprises the following reaction steps: reacting m-difluorophenyl with an organolithium reagent, reacting an obtained aryllithium intermediate with borate, quenching to obtain 2,6-difluorophenylboronic acid and 2,6-difluorophenylborate, reacting 2,6-difluorophenol obtained through oxidation with a methylating reagent, reacting the obtained 2,6-difluorophenylmethyl ether with the organolithium reagent, reacting the obtained corresponding aryllithium intermediate with carbon dioxide, reacting the obtained product with an acylchlorinating reagent to obtain 2,4-difluoro-3-methoxy benzoyl chloride, and performing cyclization, hydrolysis and the like to obtain the 1-cyclopropyl-4-oxo-7-fluoro-8-methoxy-1,4-dihydroquinolyl-3-carboxylic acid. The synthesis method has the advantages as follows: raw materials are easy to obtain; the yield in each step is high; the atom economy is high; the synthesis method is suitable for industrial application.
