A mixture of benzyl 3-(2-hydroxybenzamido)butan-2-ylcarbamate (3.2 g, 9.36 mmol) and 10% Pd/C (0.32 g) in MeOH (120 mL) was stirred under a H2 (1 atm) atmosphere (RT, 16 h). The mixture was filtered and concentrated under reduced pressure. The crude product was purified by column chromatography on silica gel, eluting with MeOH-DCM (0-20%) to afford N-(3-aminobutan-2-yl)-2-hydroxybenzamide (1.67 g, 86%) as a yellow oil.
