Reaction Conditions

Reaction Steps

1M LiOH aqueous solution (2.4 ml, 2.40 mmol) was added to a solution of 11 (0.38 g, 1.20 mmol) in dioxane (15 mL). The reaction mixture was stirred at 40° C. overnight and then was concentrated under reduced pressure. The residue was dissolved in water and concentrated HCl was added up to acidic pH to give the precipitation, which was dried by vacuum to afford 16 (0.34 g). 1H NMR (500 MHz, CD3OD): δ 2.97 (t, J=8.6 Hz, 2H), 3.99 (t, J=8.6 Hz, 2H), 7.51-7.54 (m, 2H), 7.61-7.64 (m, 2H), 7.74 (s, 1H), 7.84-7.88 (m, 3H).
