Procedure

3-chloro-5-fluoroaniline (0.074 mL, 0.73 mmol) was reacted with 8-(1-bromoethyl)-N,N-dimethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamide hydrobromide (0.09 g, 0.18 mmol)) using an analogous procedure to the one described in Example 3.03 to give 8-(1-(3-chloro-5-fluorophenylamino)ethyl)-N,N-dimethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamide (0.065 g, 75%) as a white solid. Mass Spectrum: M+H+ 474. NMR Spectrum (CDCl3): 1.61 (d, 3H), 2.90 (bs, 3H), 3.09 (bs, 3H), 3.46-3.55 (m, 4H), 3.80-3.88 (m, 4H), 4.35 (d, 1H), 4.88-4.96 (m, 1H), 5.56 (s, 1H), 6.03 (ddd, 1H), 6.27 (dd, 1H), 6.39 (ddd, 1H), 7.70 (d, 1H), 8.12 (d, 1H).
