Reaction Steps

To a solution of 6-((4-tert-butylbenzyl){4-[(4-butylphenyl)ethynyl]benzyl}amino)-2,2-dimethyl-4H-1,3-benzodioxin-4-one (71 mg, 0.12 mmol) in dioxane (2 ml) was added a solution of LiOH hydrate (25 mg, 0.60 mmol) in water (0.2 mL). The reaction mixture was heated at 80° C. for 3 hrs. Then a solution of HCl in dioxane (1 mL, 4N) and a saturated aqueous solution of NaCl (5 mL) were added and extracted with Et2O (2×10 mL). The combined organic layers were dried over Na2SO4 and the solvents were removed under reduced pressure. The residue was dissolved in a solution of HCl in Et2O (1 mL, 1N) and DCM (1 mL). Evaporation of the solvent under reduced pressure gave 57 mg (64%) of the title compound as a beige solid. HPLC, Rt: 5.7 min (purity: 79.0%). 1H NMR (CDCl3) δ: 8.08-6.85 (m, 15H), 4.69 (brs, 4H), 2.61 (t, J=7.7 Hz, 2H), 1.59 (m, 2H), 1.34 (m, 2H), 1.24 (s, 9H), 0.93 (t, J=7.3 Hz, 3H).
