Procedure
8-(1-aminoethyl)-N,N-dimethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamide (300 mg, 0.87 mmol, [α]D20°: +35° in acetonitrile) was reacted with 3-bromo-5-fluorobenzonitrile (382 mg, 1.91 mmol) using a procedure similar to the one described in Example 8.00. Purification was done by flash chromatography on silica gel eluting with 0 to 5% MeOH in DCM followed by preparative HPLC on a Waters X-Bridge system. The fractions containing the desired compound were evaporated to dryness to afford 8-(1-(3-cyano-5-fluorophenylamino)ethyl)-N,N-dimethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamide (330 mg, 82%) as a clear white solid. Mass Spectrum: M+H+ 465.
