2-amino-6-fluorobenzonitrile (111 mg, 0.82 mmol) was reacted with 8-(1-bromoethyl)-N,N-dimethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamide hydrobromide (100 mg, 0.20 mmol) using an analogous procedure to the one described in Example 3.03. The crude product was purified by flash chromatography on silica gel eluting with 0 to 10% MeOH in DCM. The solvent was evaporated to dryness. The resulting oil was crystallised from ethyl acetate to give 8-(1-(2-cyano-3-fluorophenylamino)ethyl)-N,N-dimethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamide (45.0 mg, 64.3%) as a white solid. Mass Spectrum: M+H+ 465. NMR Spectrum (DMSOd6): 1.61 (d, 3H), 2.74 (bs, 3H), 2.95 (bs, 3H), 3.49-3.62 (m, 4H), 3.69-3.77 (m, 4H), 5.17-5.26 (m, 1H), 5.61 (s, 1H), 6.33 (d, 1H), 6.56 (dd, 1H), 6.99 (d, 1H), 7.32 (dd, 1H), 7.69 (d, 1H), 7.81 (d, 1H).
