Chemical Properties

White powder

Uses

5-Chloroisatoic Anhydride was used as a reagent in the synthesis of 2-acetamidobenzamides bearing the 2-phenoxy functionality which display antiproliferative activity against certain tumor cell lines. Also used in the preparation of inhibitors of delta-5 desaturase.

Preparation

5-Chloroisatoic anhydride is prepared from 5-chloro indole (9c) by stirring in a 4:1 mixture of DMF/H2O for 16 h at room temperature.
1 H NMR (DMSO-d6): δ 11.85 (s, br., 1H), 7.96 (dd, J = 0.8, 8.7 Hz, 1H), 7.87 (dd, J = 2.3, 8.7 Hz, 1H), 7.09 (dd, J = 8.8, 0.8 Hz, 1H).
