Procedure

8-(1-bromoethyl)-N,N-dimethyl-2-((S)-2-methylmorpholino)-4-oxo-4H-chromene-6-carboxamide (110 mg, 0.20 mmol) and 4-fluoroaniline in DMA (1 mL) were stirred at 50° C. for 5 hrs. The reaction mixture was purified by preparative HPLC on a Waters X-Bridge system. The fractions containing the desired compound were concentrated. The obtained gum was triturated in diethyl ether and petroleum ether, the resulting solid was collected by filtration and dried to afford 8-(1-(4-fluorophenylamino)ethyl)-N,N-dimethyl-2-((S)-2-methylmorpholino)-4-oxo-4H-chromene-6-carboxamide (45 mg, 51%) as a white solid. Mass Spectrum: M+H+ 545. NMR Spectrum (CDCl3): 1.25 (d, 1.5H), 1.26 (d, 1.5H), 1.61 (d, 3H), 2.77-2.88 (m, 1H), 2.83 (bs, 3H), 3.06 (bs, 3H), 3.13-3.22 (m, 1H), 3.64-3.82 (m, 4H), 3.97 (bs, 1H), 3.98-4.06 (m, 1H), 4.91 (q, 1H), 5.56 (s, 1H), 6.37-6.43 (m, 2H), 6.82 (t, 2H), 7.73 (d, 1H), 8.11 (d, 1H).
