tert-Butyl 2-((2-aminoethyl)(methyl)amino)ethylcarbamate (500 mg, 2.3 mmol) was taken up in CH3CN (10 mL) along with salicylic acid (310 mg, 2.3 mmol) and EDCI (485 mg, 2.53 mmol). The resulting reaction mixture was stirred at room temperature for 18 h and then diluted with EtOAc. The organic layer was washed with saturated aqueous NaHCO3, brine, dried over Na2SO4 and concentrated under reduced pressure. The resulting residue was purified by chromatography (MeOH—CH2Cl2, 5%) to afford tert-butyl 2-((2-(2-hydroxybenzamido)ethyl)(methyl)amino)ethylcarbamate (380 mg, 49%). Mass calculated for C17H27N3O4: 337.2; found: [M+H]+=338.
