Procedure

Manganese(IV) oxide (0.72 g, 8.3 mmol) was added to methyl 3-[(dimethylamino)methyl]-5-(hydroxymethyl)benzoate (0.37 g, 1.6 mmol, from Step A) in toluene (15 mL). The mixture was heated to 105° C. for 2 hours, then was cooled to room temperature and filtered. Solvent was removed from the filtrate in vacuo to afford the product as a colorless oil (0.30 g, 82%). 1H NMR (400 MHz, CDCl3): δ 10.07 (s, 1H), 8.43 (dd, 1H), 8.25 (dd, 1H), 8.05 (dd, 1H), 3.96 (s, 3H), 3.54 (s, 2H), 2.26 (s, 6H); LCMS (M+H)+: 222.1.
