Participants

Reaction Steps

0.16 mL of aqueous 2N NaOH was added to a solution of 47 mg of 1k in 1.0 mL of dioxane and 0.5 mL water. After stirring at room temperature for one hour, the reaction mixture was made acidic (pH 2) and extracted with a mixture of n-butanol and dichloromethane. Evaporation of the organic solvents yielded 47 mg of acid 2a. 1H-NMR 200 MHz (CDCl3/CD3OD=3/1) δ: 3.20-3.65 (4H, m), 4.87 (1H, dd, J=7 Hz and J=5 Hz), 7.10 (1H, d, J=7 Hz), 7.41 (1H, d, J=7 Hz), 7.58-8.03 (8H, m), 8.29 (1H, d, 7 Hz), 8.41 (1H, d, 2 Hz)
