Reaction Steps
A 100 ml, round bottom flask was charged with anthranilic acid (500 mg, 3.65 mmol), added DMF (15 mL) under nitrogen atmosphere and stirring. Then, added N-methylmorpholine (1 mL, 9.12 mmol), aminomethylcyclopropane (311 mg, 4.38 mmol), N-ethyl-N′-dimethylaminopropylcarbodiimide (EDCI) (840 mg, 4.38 mmol) and HOBt (670 mg, 4.38 mmol). The reaction mixture was stirred at room temperature overnight. The reaction mixture was quenched with water and extracted with diethyl ether (50 mL×2). The organic extracts were combined, washed with brine, dried over MgSO4, filtered and concentrated to afford amorphous colorless 2-amino-N-(cyclopropylmethyl)benzamide (500 mg, 72% yield), which was checked by NMR and used for next step without further purification. 1H-NMR (Bruker 300 MHz, DMSO-d6) δ 0.20-1.01 (m, 4H), 1.01-1.04 (m, 1H), 3.06-3.11 (m, 2H), 6.37-8.21 (m, 7H).
