참여 물질

반응 단계

To a solution of 226 mg (1.15 mmol) 3,5-dimethoxy-phenylacetic acid in 7 ml N,N-dimethylformamide were added 244 mg (1.5 mmol) 1,1′-carbonyl-diimidazole and the solution was stirred for 30 min at room temperature. After addition of 283 mg (1 mmol) of methyl-(6-morpholin-4-yl-4-tolyl-pyridin-3-yl)-amine (as described in step f) for the preparation of Example 23), the reaction mixture was heated at 70° C. for 7 h. After cooling to room temperature, the solvent was removed in vacuo and the residue was re-dissolved in 30 ml ethyl acetate. The organic phase was washed with water (2×30 ml), brine, dried (magnesium sulfate) and evaporated. Flash chromatography gave 347 mg (75%) of the title compound as a white foam.
