Procedure

A mixture of 13.8 g of ethyl 10-chloro-2,3-dihydro-1,3-dimethyl-7-oxo-1H, 7H-pyrido[1,2,3-de]quinoxaline-6-carboxylate and 600 ml of three percent sodium hydroxide solution was heated on a steam bath for five hours. The solution was treated with decolorizing charcoal, filtered and neutralized to pH 7 with acetic acid. The product was separated by filtration, washed with water and recrystallized from N,N-dimethylformamide to provide yellow crystals of 10-chloro-2,3-dihydro-1,3-dimethyl-7-oxo-1H,7H-pyrido[1,2,3-de]-quinoxaline-6-carboxylic acid, m.p. 243°-245° C. Analysis: Calculated for C14H13ClN2O3 : %C, 57.5; %H, 4.5; %N, 9.6. Found %C, 58.0; %H, 4.3; %N, 9.7.
