実験手順

A mixture of N-(4-Naphthalen-2-ylmethyl-3-oxo-3,4-dihydro-2H-benzo[1,4]oxazin-5-yl)-oxalamic acid, I-62 (52 mg, 0.14 mmol), thiophene sulfonamide (28 mg, 0.17 mmol), EDCI (33 mg, 0.17 mmol), DMAP (22 mg, 0.17 mmol) in methylene chloride was stirred at room temperature for 24 h. Reaction was diluted with chloroform (10 mL) and washed with 6.0 M HCl (3.0 mL×4), water (3.0 mL). Chloroform layer was concentrated and the residue was purified over silica gel with chloroform:methanol (90:10) as eluant to afford N-(4-Naphthalen-2-ylmethyl-3-oxo-3,4-dihydro-2H-benzo[1,4]oxazin-5-yl)-2-oxo-2-(thiophen-2-sulfonylamino)-acetamide, P019 (7.0 mg). 1H NMR (500 MHz, DMSO-d6) 4.59 (s, 2H), 5.35 (s, 2H), 6.84 (dd, J=8.0, 1.5 Hz, 1H), 6.90 (dd, J=8.0, 8.0 Hz, 1H), 7.02 (m, 2H), 7.06 (dd, J=5.0, 3.5 Hz, 1H), 7.44 (m, 1H), 7.56 (s, 1H), 7.61 (dd, J=3.5, 1.5 Hz, 1H), 7.71-7.65 (m, 3H), 7.78 (m, 1H), 10.05 (s, 1H). MS (ESI−) Calcd. (M+) 521.6; Found: 520.7 (M−1).
