2-Methoxybenzoic acid → Tert-Butyl 3-{[(2-methoxy benzoyl)amino]methyl}piperidine-1-carboxylate

Participants

Reaction Steps

HATU (293 mg, 0.77 mmol) was added to a DMF (3 mL) solution of the compound (150 mg, 0.7 mmol) synthesized in (2), 2-methoxybenzoic acid (117 mg, 0.77 mmol), and diisopropylethylamine (0.27 mL, 1.54 mmol), and the mixture was stirred at room temperature for 24 hours. After adding ethyl acetate, the reaction mixture was washed twice with distilled water, and once with saturated brine. The organic layer was dried over magnesium sulfate, and concentrated under reduced pressure. The resulting residue was then purified using silica gel column chromatography to obtain the target (244 mg, 100%).
