Reaction Steps

tert-Butyl 2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-9-ethyl-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetate (6.6 mg, 0.012 mmol) was added to a solution of 2-amino-3-mercaptopropanoic acid (1.476 mg, 0.012 mmol) in TFA (1 mL). The reaction was stirred at 23° C. for 15 min in a 20 mL sealed scintillation vial. The mixture was poured into about 4 mL of ice water. The precipitate was collected by vacuum filtration through a glass fiber paper, washed with n-hexane (3×5 mL), and dried (vacuum oven) to give the title compound (0.8 mg) as a tan solid.
