Procedure
To a mixture of DMPU (0.7 mL) and DMF (2.8 mL) was added N-[4-chloro-3-(trifluoromethyl)phenyl]-3-(4-hydroxyphenyl)propanamide (600 mg, 1.75 mmol) and 4-chloro-N-methylpyridine-2-carboxamide (prepared as described in Bankston, D. et al. Organic Process Research and Development 2002, 6, 777-781; 328 mg, 1.92 mmol). To this solution was added KOt-Bu (590 mg, 5.25 mmol). The reaction mixture was stirred at 100° C. for 18 h and then cooled to rt, diluted with water and extracted with EtOAc and DCM. The combined organic solutions were washed with water and brine, dried over Na2SO4, filtered and concentrated to give a brown oil. Purification by column chromatography provided 100 mg of a colorless solid. 1H NMR (300 MHz, CD3OD) δ: 10.11 (br s, 0.34H), 8.41 (d, J=5.6 Hz, 1H), 8.07 (br d, J=2.2 Hz, 1H), 7.74 (br dd, J1=8.7 Hz, J2=2.1 Hz, 1H), 7.48-7.51 (m, 2H), 7.36 (d, J=8.5 Hz, 1H), 7.05 (d, J=8.5 Hz, 2H), 6.98 (dd, J1=5.6 Hz, J2=2.5 Hz, 1H), 3.34 (s, 0.84H), 3.04 (t, J=7.5 Hz), 2.92 (s, 3H), and 2.71 (t, J=7.5 Hz).
