Procedure
An aqueous (10 mL) solution of sodium hydroxide (0.53 g, 13.18 mmol) was added into the solution of 25 (1.35 g, 4.39 mmol) in THF (60 mL) and the resulting solution was stirred at room temperature for 48 h and at 60° C. for 14 h. Then the solvent was removed under reduced pressure. Water (20 mL) was added and pH was adjusted to 7 with HCl. The white solid precipitate was filtered off, washed with water and dried under vacuum. 1.22 g (95%) of white solid 26 was obtained. 1H NMR (300 MHz, DMSO-d6) δ 1.39 (br s, 11H), 1.52 (m, 2H), 1.64 (m, 2H), 2.92 (m, 2H), 6.84 (m, 1H), 7.28 (d, 2H), 7.85 (d, 2H).
