Participants

Reaction Steps

To a solution of tert-butyl 2-(7-(4-(cyclopropylmethoxy)-3-(trifluoromethyl)benzyloxy)-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetate (48.4 mg, 0.094 mmol) in DCM (1 mL) was added anisole (0.110 mL, 0.939 mmol) and TFA (0.209 mL, 2.82 mmol). The reaction mixture was stirred for 1 hour. The solvent was removed under vacuum. The residue was purified by preparative HPLC/MS to give the title compound as a solid (3.8 mg). LCMS m/z=460.4 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ ppm 0.29-0.38 (m, 2H), 0.50-0.61 (m, 2H), 1.14-1.28 (m, 1H), 2.14-2.26 (m, 1H), 2.53-2.61 (m, 1H), 2.63-2.72 (m, 1H), 2.72-2.83 (m, 1H), 3.52-3.61 (m, 1H), 3.89-4.03 (m, 3H), 4.04-4.16 (m, 1H), 5.06 (s, 2H), 6.01 (s, 1H), 6.75 (dd, J=8.72, 2.40 Hz, 1H), 7.06 (d, J=2.27 Hz, 1H), 7.18 (d, J=8.59 Hz, 1H), 7.24 (d, J=8.08 Hz, 1H), 7.61-7.72 (m, 2H), 12.27 (bs, 1H).
