Procedure

To a solution of methyl 2-[(dimethylamino)methyl]-2′-methylbiphenyl-4-carboxylate (687 mg, 2.42 mmol) in water (20 mL) at RT was treated with a 5N aqueous solution of HCl (12 mL, 60 mmol). The reaction mixture was refluxed for 4 hours, and then evaporated under vacuum. The residue was taken up in ACN and evaporated under vacuum to give the title compound as a light yellow powder (719 mg, 96%). 1H NMR (DMSO-d6) δ 13.23 (br s, 1H), 10.31 (br s, 1H), 8.47 (s, 1H), 8.03 (d, J=7.2 Hz, 1H), 7.38-7.31 (m, 4H), 7.20 (d, J=7.2 Hz, 1H), 4.32 (d, J=13.2 Hz, 1H), 3.87 (d, J=13.2 Hz, 1H), 2.61 (s, 3H), 2.50 (s, 3H), 1.98 (s, 3H). HPLC (Method A) Rt 2.52 min (Purity 100.0%).
