Participants

Reaction Steps

To a solution of tert-butyl 2-(7-(4-(cyclohexylmethyl)-3-(trifluoromethyl)benzyloxy)-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetate (50 mg, 0.092 mmol) in DCM (1 mL) was added thioanisole (0.738 mmol) and TFA (1.85 mmol). The reaction mixture was stirred for 3 h. The solvent was removed under vacuum. The residue was purified by preparative HPLC/MS to give the title compound as a solid (26.1 mg). LCMS m/z=486.4 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ ppm 0.90-1.04 (m, 2H), 1.08-1.20 (m, 3H), 1.54-1.70 (m, 6H), 2.15-2.26 (m, 1H), 2.55 (dd, J=16.29, 8.08 Hz, 1H), 2.62 (d, J=6.44 Hz, 2H), 2.65-2.72 (m, 1H), 2.72-2.83 (m, 1H), 3.52-3.63 (m, 1H), 3.91-4.01 (m, 1H), 4.05-4.14 (m, 1H), 5.12 (s, 2H), 6.01 (s, 1H), 6.77 (dd, J=8.72, 2.40 Hz, 1H), 7.07 (d, J=2.40 Hz, 1H), 7.19 (d, J=8.59 Hz, 1H), 7.44 (d, J=8.08 Hz, 1H), 7.66 (d, J=7.71 Hz, 1H), 7.74 (s, 1H), 12.27 (bs, 1H).
