tert-Butyl 2-(7-(3-cyano-4-isopropoxybenzyloxy)-9-iodo-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetate (100 mg, 0.171 mmol) in NMP (2 mL) was added copper(I) iodide (162 mg, 0.853 mmol) and sodium methanesulfinate (102 mg, 0.853 mmol). The reaction mixture was heated at 125° C. under nitrogen protection for 8 h. The solid was filtered and washed with ethyl acetate. The filtrate was washed with water and dried over anhydrous Na2SO4. The solvent was evaporated and the residue was purified by column chromatography to give the title compound (36 mg). LCMS m/z=539.6 [M+H]+; 1H NMR (400 MHz, CDCl3) δ ppm 1.36 (s, 9H), 1.40 (d, J=6.0 Hz, 6H), 2.46-2.55 (m, 1H), 2.74 (dd, J=16.0, 9.0 Hz, 1H), 2.88-2.98 (m, 1H), 3.12 (s, 3H), 3.08-3.14 (dd, J=16.0, 3.6 Hz, 1H), 3.95-4.02 (m, 1H), 4.05-4.20 (m, 2H), 4.62-4.69 (m, 1H), 5.03 (s, 2H), 6.95 (dd, J=8.8, 2.4 Hz, 1H), 6.98 (d, J=8.8 Hz, 1H), 7.20 (d, J=8.8 Hz, 1H), 7.41 (d, J=2.4 Hz, 1H), 7.59 (dd, J=8.7, 2.2 Hz, 1H), 7.65 (d, J=2.2 Hz, 1H).
