tert-Butyl 2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-9-cyclopropyl-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetate (9.2 mg, 0.017 mmol) was added to a solution of 2-amino-3-mercaptopropanoic acid (2.013 mg, 0.017 mmol) in TFA (1 mL) and the resulting mixture was stirred at room temperature for 15 min in a 20 mL sealed scintillation vial. After 15 min, the reaction mixture was poured into approximately 4 mL of ice water. A precipitate formed and was collected by vacuum filtration. The solid was washed with n-hexane (3×5 mL) and dried (vacuum oven) to give the title compound as a off-white solid (5.5 mg).
