실험 절차

To a mixture of 45 mg (0.2 mmol) of 1-chloro-4-hydroxy-isoquinoline-3-carboxylic acid (from example A-1 d), 76 mg (0.2 mmol) of benzotriazol-1-yl-(bis-dimethylamino-methylene)-oxonium hexafluoro phosphate (HBTU), 18 μl 2-methoxy-ethylamine (0.2 mmol), and 1 ml of dichloromethane were added 96 μl (0.55 mmol) of ethyl-diisopropyl-amine with stirring. Stirring was continued at ambient temperature for 12 days. The product was isolated from the reaction mixture by flash column chromatography on silica gel using hexanes:ethyl acetate (9:1) as the eluent to give a white solid. 8.8 mg of the title compound were obtained; MS-(+)-ion: M+1=281.0.
