실험 절차

Ethyl 2-(6-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-2,3-dihydro-1H-benzo[d]pyrrolo[1,2-a]imidazol-3-yl)acetate (0.109 g, 0.224 mmol) was dissolved in dioxane (2.5 mL) and 1.0 M aqueous lithium hydroxide (0.672 mL, 0.672 mmol) was added. The reaction mixture was stirred at room temperature for 1.5 h and then acidified (pH 2) with 1.0 M HCl. The reaction mixture was extracted three times with EtOAc and the combined extracts were dried over sodium sulfate, filtered and concentrated under reduced pressure to provide the title compound (103 mg). LCMS m/z=459.3 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ ppm 1.54-1.65 (m, 2H), 1.67-1.79 (m, 2H), 1.80-1.91 (m, 2H), 2.05-2.14 (m, 2H), 2.42-2.53 (m, 1H), 2.89 (d, J=7.1 Hz, 1H), 2.95-3.22 (m, 2H), 3.33-3.43 (m, 1H), 3.78-3.87 (m, 1H), 4.03-4.12 (m, 1H), 4.14-4.23 (m, 1H), 5.09 (s, 2H), 6.88 (d, J=2.4 Hz, 1H), 6.97 (dd, J=8.8, 2.5 Hz, 1H), 7.48 (d, J=8.2 Hz, 1H), 7.57 (d, J=8.1 Hz, 1H), 7.62 (d, J=8.8 Hz, 1H), 7.68 (s, 1H).
