Versuchsvorschrift

A solution of 15.85 g (0.05 mole) of 2-amino-3-benzoyl-5-chlorobenzeneacetic acid, ethyl ester dissolved in 100 ml of dry tetrahydrofuran was added dropwise to a suspension of 4.0 g (0.105 mole) of lithium aluminum hydride in 50 ml of dry tetrahydrofuran. Gentle reflux was maintained during the addition. Reflux was continued for 2 hours after completion of the addition. The mixture was cooled and carefully treated with 4 ml of water, 4 ml of 15% sodium hydroxide and 12 ml of water. The resulting mixture was filtered, the filtrate stripped and the resulting residue recrystallized from toluene. The titled compound, 10.5 g (70%) having a m.p. of 130°-132° C. was obtained.
