Participants

Reaction Steps

To a solution of 2-aminomethyl-5-nitro-phenylamine (2.84 g, 17 mmol) in dry THF (150 mL) and triethylamine (12 mL, 85 mmol) was added tert-butyl bromoacetate (5 mL, 34 mmol). The mixture solution was stirred at room temperature for 16 hours and concentrated. Chromatography of the resulting residue on silica gel with methylene chloride and methanol (50:1) gave 2.15 g of (2-amino-4-nitro-benzylamino)-acetic acid tert-butyl ester (45%): 1H NMR (300 MHz, CDCl3) δ 7.58 (dd, 1H), 7.55 (5, 1H), 7.22 (d, 1H), 5.2 (br, 2H) 3.95 (s, 2H), 3.39 (s, 2H), 1.58 (s, 9H); MS (m/e): 282.3 (M+1).
