Participants

Reaction Steps

To a stirred solution of methyl 3-amino-5-bromo-2-methylbenzoate (5 g, 20.57 mmol) and tert-butyl (4-oxocyclohexyl)carbamate (5.67 g, 26.74 mmol) in methanol (50 mL), acetic acid (1.2 g, 20.57 mmol) was added and reaction stirred at room temperature for 4 h. Then sodium cyanoborohydride (1.68 g, 26.74 mmol) was added and reaction stirred 18 h. On completion, solvent was removed under reduced pressure; water was added and extracted with DCM. Combined organic were dried, concentrated and purified by column chromatography using silica (100-200 mesh size) to afford the desired compound (3 g, 33%).
