실험 절차

2-Amino-5-bromo-N,N-dimethyl-benzamide (2.00 g, 8.22 mmol), diisopropylethylamine (6.5 ml, 37.32 mmol), 4-morpholinecarbonyl chloride (4.3 ml, 37.46 mmol), and chloroform (20 ml) were combined and stirred for 18 hours at 50° C. Water was added to the mixture, and the organic layer was extracted. The organic layer was dried over sodium sulfate, concentrated in vacuo, and the crude material was purified by flash chromatography (50% to 100% ethyl acetate in hexanes) to give 1.13 g (39%) of morpholine-4-carboxylic acid (4-bromo-2-dimethylcarbamoyl-phenyl)-amide. 1H-NMR (250 MHz, DMSO-d6) δ 8.67 (s, 1H), 7.56-7.45 (m, 2H), 7.42 (t, J=9.3 Hz, 4H), 3.35-3.28 (m, 4H), 2.96-2.86 (m, 6H); MS: m/z 356.0+358.1 (M+H+).
