実験手順

To a solution of N-(2-aminoethyl)-glycine ethyl ester 2HCl (1.10 g, 5.0 mmol), prepared as described by Will (D. W. Will et al., Tetrahedron, 1995, 51, 12069.), in dichloromethane (50 mL) was slowly added triethylamine (2.02 g, 20 mmol) at room temperature. Then benzothiazole-2-sulfonyl chloride (1.19 g 5.0 mmol) in dichloromethane (10 mL) was added to the reaction mixture at room temperature for 5 min. The resulting reaction mixture was stirred for additional 2 h. at room temperature and washed with water (30 mL). The organic layer was dried over MgSO4 and filtered. The filtrate was evaporated to remove solvent to give desired product (1.60 g, 92%) as a solid. 1H NMR (500 MHz; DMSO-d6) δ 8.28 (d, 1H), 8.19 (d, 1H), 7.69˜7.63 (m, 2H), 4.03 (q, 2H), 3.24 (s, 2H), 3.13 (t, 2H), 2.62 (t, 2H), 1.15 (t, 3H).
