Reaction Steps
1-Oxo-6,7-dihydro-1H,5H-pyrido[3,2,1-ij]quinoline-2-carboxylic acid ethyl ester (1.0 g) was placed in round bottom flask and to that, mixture of H2SO4/HNO3 (1:1) was added and stirred for 3 hours at 0° C. The reaction mixture was poured on ice and precipitate was filtered off affording 900 mg of title product (LC/MS: 95%).
