Reaction Steps
A stirred mixture of methyl 1-(biphenyl-4-ylcarbonyl)piperidine-4-carboxylate (0.10 g, 0.31 mmol), sodium hydroxide (25 mg, 0.62 mmol), water (4 mL) and tetrahydrofuran (1 mL) is heated at 50° C. for 3 h. Solvents are removed under reduced pressure giving a residue. The residue is redissolved 1M aqueous HCl (4 mL) and extracted with EtOAc (3×4 mL). The organic layers are combined, dried (Na2SO4), filtered and concentrated under reduced pressure to give 82 mg (93%) of 1-(biphenyl-4-ylcarbonyl)piperidine-4-carboxylic acid. m/z=310 [M++H].
