참여 물질

반응 단계

To a solution of 8-amino-5-bromo-1-methyl-1,2,3,4-tetrahydroquinoline-7-carboxylic acid (600 mg, 2.10 mmol) in DMF (7 mL) at rt was added (1S,2S)-2-aminocyclohexanol (242 mg, 2.10 mmol), BOP (1.16 g, 2.63 mmol), and Et3N (0.59 mL, 4.21 mmol). The mixture was stirred at rt for 2 h. The resulting solution was quenched with 10% aqueous NaHCO3 and extracted with ethyl acetate. The combined extracts were washed with water and brine, dried (Na2SO4), and concentrated to afford 8-amino-5-bromo-N-[(1S,2S)-2-hydroxycyclohexyl]-1-methyl-1,2,3,4-tetrahydroquinoline-7-carboxamide in pure form.
