Procedure
Step A To a solution of N-Boc-1,4-phenylene diamine (Aldrich, 1.00 g, 4.82 mmol) in CH2Cl2 (12 ml) were added N,N-diisopropylethylamine (1.26 g, 9.76 mmol) and ethyl bromoacetate (Aldrich, 813 mg, 4.87 mmol). The mixture was allowed to stir at rt overnight and then taken up in EtOAc (300 ml) and washed with sat. aqueous Na2CO3, water and brine. The organic layer was dried over Na2SO4 and concentrated in vacuo to give ethyl 2-(4-(tert-butoxycarbonylamino)phenylamino)acetate as a light brown oil (1.33 g, 94%).
