Procedure

To tert-butyl 2-(7-(3-cyano-4-cyclohexylbenzyloxy)-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetate (51.4 mg, 0.106 mmol) was added a solution of DL-cysteine (19.87 mg, 0.159 mmol) in trifluoroacetic acid (1 mL). The mixture was stirred at room temperature for 15 min. The reaction mixture was poured into an ice water to form a solid. The solid was filtered and washed with water to provide the title compound as an off-white solid (41.8 mg). LCMS m/z=429.6 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ ppm 1.19-1.31 (m, 1H), 1.32-1.55 (m, 4H), 1.69-1.75 (m, 1H), 1.75-1.85 (m, 4H), 2.14-2.25 (m, 1H), 2.56 (dd, J=12.00, 8.00 Hz, 1H), 2.67 (dd, J=12.00, 8.00 Hz, 1H), 2.71-2.78 (m, 1H), 2.79-2.90 (m, 1H), 3.57 (t, J=7.39 Hz, 1H), 3.87-3.99 (m, 1H), 4.02-4.16 (m, 1H), 5.08 (s, 2H), 6.00 (s, 1H), 6.76 (dd, J=8.72, 2.40 Hz, 1H), 7.05 (d, J=2.40 Hz, 1H), 7.18 (d, J=8.72 Hz, 1H), 7.51 (d, J=8.21 Hz, 1H), 7.72 (dd, J=8.21, 1.64 Hz, 1H), 7.81 (d, J=1.52 Hz, 1H), 12.26 (bs, 1H).
