Participants

Reaction Steps

A solution of 6-chloro-8-(4-ethylphenyl)-2-(trifluoromethyl)-2H-chromene-3-carboxylic acid 51.9 mg (0.136 mmole) in 2.0 mL of ethanol was treated with 1.345 mL of 0.1008N NaOH. The resultant mixture was lyophilized to provide a quantitative yield of a yellow solid: 1H NMR (CD3OD/400 MHz) 1.25 (t, 3H, J=7.6 Hz), 2.67 (q, 2H, J=7.6 Hz), 5.82 (q, 1H, J=7.2 Hz), 7.21-7.25 (m, 4H), 7.38-7.40 (m, 3H).
