A second aliquot of 2-aminoethanol (38 μL, 0.63 mmol) was added and the resulting mixture was heated at 90° C. overnight. The reaction mixture was then concentrated under reduced pressure, the residue was washed with water, dried over anhydrous sodium sulfate, filtered and evaporated under reduced pressure to give 70 mg of 2-(7-methoxy-6-nitro-quinolin-2-ylamino)-ethanol as a solid without further purifications. MS=264 [M+H]+.
