Procedure

[3-(6-Morpholine-4-yl-4-oxo-4H-pyran-2yl)-phenyl]carbamic acid tert-butyl ester (3.4 g, 9.2 mmol) was dissolved in 25% trifluoroacetic acid in dichloromethane mixture (30 ml) and stirred for 1 hour at room temperature. The reaction was concentrated in vacuo, precipitated with saturated NaHCO3, filtered, washed with diethyl ether and dried to yield (3-amino-phenyl)-6-morpholin-4-yl-pyran-4-one as a white solid (2.1 g, 85%). m/z (LC-MS, ESP): 273 (M++1).
