To a suspension of methyl 4-(2-amino-ethoxy)benzoate hydrochloride (0.232 g, 1 mmol) in THF (6 ml) was added benzoyl chloride (0.140 g, 1 mmol) followed by triethylamine (0.121 g, 1.2 mmol). The reaction mixture was stirred for 1 h and then diluted with ethyl acetate. The organic layer was washed with 0.5 M aqueous HCl, saturated sodium bicarbonate solution, and brine. The organic layer was concentrated in vacuo to give methyl 4-(2-benzenecarbonylamino-ethoxy)benzoate which was directly used in the next step.
