2-Methoxy-4-phenethylpyridine (22.0 g, 102 mmol) was stirred in concentrated hydrochloric acid (200 mL) at 120° C. for 18 h and then concentrated. The residue was dissolved in MeOH (100 mL) and made basic with aqueous 6 N NaOH and re-concentrated until most of the solvent had been removed. The solids were filtered off, washed with water and dried under vacuum to provide the title compound (21.3 g, 95%) as a beige solid: 1H NMR (500 MHz, DMSO-d6) δ 11.31 (br s, 1H), 7.28-7.21 (m, 5H), 7.17 (t, J=7.1 Hz, 1H), 6.10-6.08 (m, 2H), 2.85-2.82 (m, 2H), 2.70-2.67 (m, 2H).
