실험 절차

A solution of methyl 4-(aminomethyl)benzoate (1.00 g, 4.96 mmol), 2,4-dinitrobenzenesulfonyl chloride (1.39 g, 5.21 mmol), DCM (16.5 mL) and pyridine (481 uL, 5.95 mmol) was treated with Hunig's base (2.17 mL, 12.4 mmol) and stirred for 2 h. The reaction was concentrated, taken into EtOAc and washed with 2M aq. HCl 2×, water, brine, dried (MgSO4) and concentrated to afford a brown oil used crude in the next reaction. MS: cal'd 396 (MH+), exp 396 (MH+).
