Reaction Steps

To a stirred solution of methyl 3-amino-2-methyl-5-(trifluoromethyl)benzoate (2.5 g, 10.7 mmol) and cyclopentanone (4.5 g, 53.49 mmol) in methanol (25 mL) was added acetic acid (1.98 g, 21.44 mmol). After 3 h, sodium cyanoborohydride (1.68 g, 24.3 mmol) was added and the reaction stirred overnight. On completion, the solvent was removed under reduced pressure and crude material was purified by column chromatography to afford methyl 3-(cyclopentylamino)-2-methyl-5-(trifluoromethyl)benzoate (1.8 g, 55.9%).
