실험 절차

3-Hydroxy-4-methylbenzoic acid (530 mg, 3.5 mmol), 3-amino-4-(4-morpholino)benzotrifluoride (890 mg, 3.6 mmol), and DMAP (150 mg, 1.3 mmol) were suspended in 20 mL dry toluene in a 2-neck flask with an attached Dean-Stark trap under N2. The mixture was stirred in a 130° C. oil bath and brought to a boil before PCl3 (0.18 mL, 2 mmol) was added dropwise by glass/Teflon syringe over 15 minutes. Heating was continued an additional 45 minutes. After cooling, the mixture was diluted with brine and ethyl acetate, and acidified with 1 N HCl. After extraction, the organic layer was dried with Na2SO4, concentrated, and purified by flash chromatography (2% MeOH in CH2Cl2). The isolated material was packed into a small filtration apparatus and rinsed with a small amount of CH2Cl2 to provide the title compound as a white solid. 1H NMR (Varian, 400 MHz, DMSO-d6) d: 9.83 (s, 1H), 9.50 (s, 1H), 8.45 (s, 1H), 7.48 (m, 1H), 7.43 (m, 1H), 7.34 (s, 1H), 7.31 (m, 1H), 7.25 (m, 1H), 3.78 (m, 4H), 2.90 (m, 4H), 2.18 (s, 3H).
