Participants

Reaction Steps

A solution of 38.1 mg (0.101 mmole) of (2R)-(−)-2-(trifluoromethyl)-7-(2,3,5-trimethylphenoxy)-2H-chromene-3-carboxylic acid in 1.5 mL of ethanol was treated with 1.00 mL of 0.1008N NaOH. The resultant mixture was lyophilized to provide 48.4 mg (quant.) of an off-white solid: MS (ES+) 379 (M+1, 100); 1H NMR (CD3OD/400 MHz) 2.01 (s, 3H), 2.24 (s, 3H), 2.26 (s, 3H), 5.76 (q, 1H, J=7.4 Hz), 6.28 (d, 1H, J=2.4 Hz), 6.38 (dd, 1H, J=8.3 Hz, J=2.4 Hz), 6.63 (s, 1H), 6.87 (s, 1H), 7.11 (d, 1H, J=8.3 Hz), 7.38 (s, 1H); 19F NMR (CD3OD/400 MHz) 80.2 (d, 3F, J=7.7 Hz).
