Reaction Steps

3,4-difluoroaniline (0.105 mL, 1.06 mmol) was reacted with 8-(1-bromoethyl)-N,N-dimethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamide hydrobromide (130 mg, 0.27 mmol) using a procedure similar to the one described in Example 3.00 to give 8-(1-(3,4-difluorophenylamino)ethyl)-N,N-dimethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamide (35.0 mg, 28.8%) as a white solid. Mass Spectrum: M+H+ 458. NMR Spectrum: (DMSOd6) 1.50 (d, 3H), 2.70 (s, 3H), 2.94 (s, 3H), 3.50-3.63 (m, 4H), 3.71-3.79 (m, 4H), 4.92-5.01 (m, 1H), 5.60 (s, 1H), 6.25 (d, 1H), 6.46 (ddd, 1H), 6.54 (d, 1H), 7.05 (dd, 1H), 7.54 (d, 1H), 7.78 (d, 1H).
