RESUMO
Uma metodologia rápida e eficiente foi desenvolvida para separação de isômeros de isatinas utilizando a técnica de cromatografia contracorrente de alta velocidade. Os isômeros de derivados de isatinas foram preparados segundo a metodologia de Sandmeyer e separados com o sistema de solventes hexano:acetato de etila:etanol:água 1:0,5:0,5:1 (v/v/v/v).
