Procedure

To a stirred solution of methyl 3-amino-5-bromo-2-methylbenzoate (2 g, 8.23 mmol) and 1-methylpiperidin-4-one (1.86 g, 16.46 mmol) in methanol (20 mL), acetic acid (0.5 g, 8.23 mmol) was added and reaction stirred at room temperature for 3 h. Then sodium cyanoborohydride (0.622 g, 9.87 mmol) was added and reaction stirred overnight. On completion, solvent was removed under reduced pressure and crude material was purified by column chromatography to afford the desired compound (0.9 g, 33%).
