Reaction Steps

To a solution of 2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetic acid (34 mg, 0.074 mmol) dissolved in DCM (0.500 mL) and cooled to 0° C. was added NCS (9.92 mg, 0.074 mmol). The reaction was stirred at 0° C. for 15 min in a 20 mL sealed scintillation vial. After 15 min, the reaction mixture was diluted with DCM and washed with water (2×10 mL), washed with sodium thiolsulfate pentahydrate (aq.) (2×10 mL), dried over MgSO4 and filtered. The filtrate was concentrated under reduced pressure to give the title compound as a light yellow solid (32 mg). LCMS m/z=492.3 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ ppm 1.54-1.73 (m, 4H), 1.80-1.89 (m, 2H), 1.95-2.05 (m, 2H), 2.24-2.35 (m, 1H), 2.52-2.58 (m, 1H), 2.77-2.87 (m, 1H), 2.94 (dd, J=16.36, 4.11 Hz, 1H), 3.21-3.29 (m, 1H), 3.64-3.72 (m, 1H), 3.95-4.05 (m, 1H), 4.11-4.19 (m, 1H), 5.18 (s, 2H), 6.87 (dd, J=8.78, 2.46 Hz, 1H), 6.98 (d, J=2.27 Hz, 1H), 7.29 (d, J=8.84 Hz, 1H), 7.63 (d, J=7.96 Hz 1H), 7.69-7.76 (m, 2H), 12.35 (bs, 1H).
