反応手順

To a solution of 8-amino-5-bromoquinoline-7-carboxylic acid (1.00 g, 3.74 mmol) in 20 mL of dichloromethane was added (1H-1,2,3-benzotriazol-1-yloxy)[tris(dimethylamino)]phosphonium hexafluorophosphate (1.99 g, 4.49 mmol), (1S,2S)-2-aminocyclohexanol (0.517 g, 4.49 mmol), and triethylamine (1.04 mL, 7.49 mmol). After 3 h, a brown solid was collected and washed with dichloromethane and water to provide 8-amino-5-bromo-N-[(1S,2S)-2-hydroxycyclohexyl]quinoline-7-carboxamide that gave a mass ion (ES+) of 365.9 (81Br) for [M+H]+.
