反应详情

The crude amine was dissolved in CH2Cl2 (5 mL) and Et3N (222 μL, 1.6 mmol) and crude cyclobutylsulfamoyl chloride (136 mg, ca. 0.8 mmol) were added and the reaction was stirred at RT for 30 min. The reaction was evaporated under reduced pressure and diluted with MeCN:DMSO (1:1, 2 mL) and filtered. The filtrate was injected on to a reverse phase HPLC system and the title compound was isolated, after basic workup, as a yellow gum (4 mg, 1% over 2 steps). 1H NMR (CDCl3, 500 MHz) δ 7.52-7.48 (2H, m), 7.41 (1H, t, J=8.6 Hz), 7.31-7.23 (3H, m), 6.98 (2H, t, J=8.8 Hz), 6.02 (1H, s), 4.49 (1H, s), 4.10 (1H, d, J=8.4 Hz), 3.96 (2H, s), 3.85 (3H, s), 3.82-3.73 (1H, m), 2.30-2.21 (2H, m), 1.90-1.79 (2H, m), 1.73 (6H, s), 1.72-1.63 (2H, m). MS (ES+) C24H29FN4O2S requires 456: found: 457 (M+H+).
