실험 절차

16 mg (0.24 mmol) of imidazole, 48 mg (0.48 mmol) of triethylamine and 11 mg (0.24 mmol) of formic acid are introduced into 4 ml dichloromethane under argon, cooled to 0° C. and treated dropwise with a solution of 30 mg (0.24 mmol) of oxalyl dichloride in dichloromethane. The mixture is allowed to warm to 20° C. and subsequently 100 mg (0.24 mmol) of N-[2-(4-aminophenyl)-5,7-dimethyl-imidazo[5,1-f][1,2,4]triazin-4-yl]-N-(3,4,5-trimethoxyphenyl)amine from example 3 are added thereto. It is stirred overnight and then washed with aqueous sodium hydrogencarbonate solution. The organic phase is dried and purified by flash chromatography (dichloromethane/methanol 100:1).
