To a solution of 1-benzyl 4-tert-butyl 2-(biphenyl-4-ylmethyl)succinate (90 mg, 0.209 mmol) in DCM (1 ml), TFA (0.322 ml, 4.18 mmol) was added. The reaction mixture was allowed to stir for 1 hour, and then concentrated under reduced pressure to give 4-(benzyloxy)-3-(biphenyl-4-ylmethyl)-4-oxobutanoic acid (78 mg); Retention time=1.48 minutes (condition B); MS (m−1)=373.2.
