Participants

Reaction Steps

A solution of 53.8 mg (0.148 mmole) of (2R)-(−)-7-(2,5-dimethylphenoxy)-2-(trifluoromethyl)-2H-chromene-3-carboxylic acid in 1.5 mL of ethanol was treated with 1.47 mL of 0.1008N NaOH. The resultant mixture was lyophilized to provide 55.6 mg (97%) of an off-white solid: MS (ES+) 365 (M+1, 100); 1H NMR (CD3OD/400 MHz) 2.09 (s, 3H), 2.28 (s, 3H), 5.77 (q, 1H, J=7.3 Hz), 6.31 (d, 1H, J=2.4 Hz), 6.41 (dd, 1H, J=8.3 Hz, J=2.3 Hz), 6.78 (s, 1H), 6.94 (d, 1H, J=7.7 Hz), 7.14 (m, 2H), 7.38 (s, 1H); 19F NMR (CD3OD/400 MHz) 80.2 (d, 3F, J=7.7 Hz).
