実験手順

A mixture of 1-(3,4-dihydroisoquinolin-2(1H)-yl)-3-(3-(1-((2-(trimethylsilyl)ethoxy)methyl)-1H-benzo[d]imidazol-4-yl)phenoxy)propan-2-ol (265 mg, 0.5 mmol) in EtOH (20 mL) and conc. HCl (1 mL) was stirred at 80° C. overnight. The reaction was adjusted to pH 9 by aq. NaHCO3. The mixture was then extracted with DCM and the combined organic layers dried over Na2SO4 and concentrated to give the crude product. The crude product was purified by pre-HPLC to afford the desired product (50 mg, Yield 25%). 1H NMR (400 MHz, DMSO-d6) δ 8.43 (s, 1H), 8.35 (s, 2H), 7.65 (br.s, 2H), 7.49 (m, 1H), 7.21 (dd, J=7.6 Hz, 1H), 7.12-7.06 (m, 5H), 4.53-4.39 (m, 3H), 4.14 (s, 2H), 2.83-2.57 (m, 6H). LCMS (m/z): 400.1 (M+1).
