Procedure
A mixture of tert-butyl 2-(2-hydroxybenzamido)propylcarbamate (2.4 g, 8.16 mmol) in saturated HCl-MeOH (50 mL) was stirred (RT, 2 h) and concentrated under reduced pressure to afford N-(1-aminopropan-2-yl)-2-hydroxybenzamide (1.8 g, 96%) as a white solid. Mass calculated for C10H14N2O2=194.23; found: [M+H]+=195.2.
