Reaction Steps
A mixture of ethyl 2-(7-(4-chloro-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetate (50.9 mg, 0.113 mmol), pyrrolidine (0.047 mL, 0.563 mmol), diacetoxypalladium (1.264 mg, 5.63 μmol), biphenyl-2-yl-di-tert-butylphosphine (3.36 mg, 11.0 μmol) and sodium 2-methylpropan-2-olate (27.1 mg, 0.282 mmol) in dioxane (3 mL) was heated under microwave irradiation at 120° C. for 2 h. The mixture was purified by HPLC. Fractions containing product were basified with 1 M NaHCO3 and concentrated. The residue was extracted with 0.5 M citric acid and CH2Cl2. The organics were dried over MgSO4, filtered, and concentrated to give the title compound as a white solid (17.8 mg). LCMS m/z=487.4 [M+H]+.
