实验过程

18 μl of 1,8-diazabicyclo[5.4.0]undec-7-ene were added to a solution of 21 mg of 7-chloro-6-(2,5-dimethylpyrrol-1-ylamino)-1-ethyl-4-oxo-1,4-dihydroquinolonecarboxylic acid (Example 36) in 3 ml of acetonitrile and stirred at room temperature for 30 minutes. Then 36 μl of chloromethyl pivalate were added, and reaction was allowed to take place at room temperature for 5 days. The resulting precipitate was filtered off with suction to afford 3.3 mg of pure product.
