実験手順

4.6 grams (0.02 mol) of dimethylphosphinylmethyl anthranilate and 4.6 grams (0.02 mol) of 4-chloro-8-trifluoromethylquinoline are kept at 80° C for about 31/2 hours in 15 ml of isopropanol and 2.3 ml of concentrated aqueous hydrochloric acid. After removing the solvents and excess hydrochloric acid, the free base of the ester is liberated at 0° C. The dimethylphosphinyl-methyl N-(8-trifluoromethyl-4-quinolyl)-anthranilate obtained is identical to that prepared in Example (2a). Yield 7.6 grams (90% of theory).
