反応手順
To a mixture of 8.7 mg of 8-(cyclohexylmethoxy)-2-methylimidazo[1,2-a]pyridine-3-carboxylic acid, 5.1 mg of cyclopropylamine, 4.1 mg of 1-hydroxybenzotriazole, 1 ml of DMF, and 28 μl of diisopropylethylamine was added 50 mg of polystyrene N-cyclohexylcarbodiimide-N′-propyloxymethyl (PS-Carbodiimide manufactured by Biotage), followed by stirring at room temperature for 16 hours. Subsequently, 1 ml of DMF, 50 mg of macroporious triethylammonium methylpolystyrene carbonate (MP-Carbonate manufactured by Biotage) and 50 mg of polystyrene methyl isocyanate (PS-Isocyanate manufactured by Biotage), followed by stirring at room temperature for 3 hours. The resin of the reaction mixture was removed by filtration and the filtrate was concentrated under reduced pressure. The obtained residue was purified by preparative HPLC (high performance liquid chromatography) to obtain 8.7 mg of 8-(cyclohexylmethoxy)-N-cyclopropyl-2-methylimidazo[1,2-a]pyridine-3-carboxamide.
