Versuchsvorschrift

Under a nitrogen atmosphere, ethoxyacetyl chloride (1.4 g, 11 mmol) was added dropwise to a solution of N4-{[3-(4-fluorophenyl)isoxazol-5-yl]methyl}-N2,N2-bis(4-methoxybenzyl)-5,6-dimethylpyridine-2,3,4-triamine (5.898 g, 10.39 mmol) and triethylamine (2.2 mL, 15 mmol) in dichloromethane (30 mL) at 0° C. After the reaction was stirred for 0.7 hours, an analysis by HPLC indicated the presence of starting material, and additional ethoxyacetyl chloride (0.54 g) was added. The stirring was continued, and after 1.5 hours, the reaction mixture was diluted with dichloromethane and washed sequentially with saturated aqueous potassium carbonate, water, and brine; dried over sodium sulfate, filtered, and concentrated under reduced pressure to provide 6.2 g of N-[2-[bis(4-methoxybenzyl)amino]-4-({[3-(4-fluorophenyl)isoxazol-5-yl]methyl}amino)-5,6-dimethylpyridin-3-yl]-2-ethoxyacetamide as a yellow oil.
