実験手順: To a stirred solution of 6.0 g of 1-(3-tert-butyl-5-(6-hydroxynaphthalen-2-yl)-4-methoxyphenyl)pyrimidine-2,4(1H,3H)-dione (14.4 mmol, 1.0 equivalent) in 60 mL of N,N-dimethylformamide was added 4.0 g of 325-mesh potassium carbonate (29 mmol, 2.0 equivalents). 1,1,1,2,3,3,3-heptafluoropropane-2-sulfonyl fluoride (3.6 g, 14.3 mmol, 1.0 equivalents) was added over 30 minutes, and the mixture was stirred for 2 hours. An additional portion of 1,1,1,2,3,3,3-heptafluoropropane-2-sulfonyl fluoride (0.21 g, 0.83 mmol, 0.06 equivalents) was added, and the mixture was stirred for 1.5 hours. The inorganic solids were separated by filtration, and the flask and filter cake were rinsed with 75 mL of ethyl acetate. The solution was diluted with an additional 75 mL of ethyl acetate and the resultant solution was washed four times with 50 mL portions of 10 wt % aqueous sodium chloride, followed by 50 mL of saturated aqueous sodium chloride solution. The organic solution was dried over sodium sulfate, the drying agent was filtered off and the organic solution was concentrated in vacuo. The resultant oil was dissolved in 7 mL of ethyl acetate, which resulted in crystallization after stirring for a few minutes. Heptanes (90 mL) were added slowly to the stirred mixture. The product was isolated by filtration, washed with 20 mL of heptanes and dried in vacuo with heating at 50° C. The title compound was isolated as a white solid (8.30 g, 89% yield). 1H NMR (400 MHz, CDCl3) δ ppm 8.05 (s, 1H), 7.95 (d, J=9.6 Hz, 1H), 7.93 (d, J=9.6 Hz, 1H), 7.83 (dd, J=8.5, 1.7 Hz, 1H), 7.78 (d, J=2.4 Hz, 1H), 7.40 (dd, J=8.9, 2.4 Hz, 1H), 7.36 (d, J=7.9 Hz, 1H), 7.27-7.23 (m, 2H), 5.81 (d, J=7.9 Hz, 1H), 3.29 (s, 3H), 1.46 (s, 9H) (NH not observed in this spectrum). 13C NMR (101 MHz, CDCl3) δ ppm 162.7 (C), 157.5 (C), 149.8 (C), 146.9 (C), 145.0 (C), 144.5 (CH), 137.2 (C), 135.1 (C), 133.0 (C), 132.2 (C), 132.2 (C), 130.5 (CH), 128.5 (CH), 128.1 (CH), 127.4 (CH), 127.2 (CH), 124.4 (CH), 119.9 (CH), 118.9 (CH), 102.4 (CH), 60.9 (CH3), 35.8 (C), 30.8 (CH3). 19F NMR (564 MHz, DMSO) δ ppm −71.08 (6F), −167.87 (1F).
