Procedure
Next, to the solution of the crude tert-butyl 3-(1-(2-(benzyloxy)-2-oxoethyl)cyclopentanecarboxamido)-4-(biphenyl-4-yl)butanoate (38 mg) in DCM (0.7 ml), TFA (0.263 ml, 3.42 mmol) is added. After stirring for 1 hour, the reaction mixture is concentrated to give crude 3-(1-(2-(benzyloxy)-2-oxoethyl)cyclopentanecarboxamido)-4-(biphenyl-4-yl)butanoic acid (39 mg).
