実験手順
A mixture of the so-prepared 6-fluorocarbostyril (2.9 gm, 0.018 mole) and 30.0 ml of phosphorous oxychloride was refluxed for 1.5 hr. Most of the excess phosphorous oxychloride was then distilled off under aspirator vacuum and the residue poured over crushed ice. The reaction mixture was made nearly neutral with 50% sodium hydroxide. The crude solid product was collected by filtration, taken up in
