Participants

Reaction Steps

To a stirred solution of ethyl 1-(4-amino-3-(cyclopropylmethoxy)phenyl)cyclopentanecarboxylate (1.2 g, 4.0 mmol) in dry CCl4 (60 mL), NBS (0.427 g, 3.2 mmol) was added at 0° C. The reaction mixture was allowed to stir for 3 at room temperature to complete the reaction. The reaction mixture was diluted with water, extracted with DCM (2×50 mL), the combined organic extracts were dried over Na2SO4, filtered and concentrated under reduced pressure. The crude reaction mixture was purified by column chromatography to yield ethyl 1-(4-amino-3-bromo-5-(cyclopropylmethoxy)phenyl)cyclopentanecarboxylate (920 mg) as a yellow solid.
