反应条件: temp:150.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of (S)-6-(2-chloro-4-((tetrahydrofuran-3-yl)oxy)-7-((2-(trimethylsilyl)ethoxy)-methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-2-methylbenzo[d]oxazole (1 equiv), 4-amino-3-chloro-N-methylbenzamide (1.2 equiv), tris(dibenzylideneacetone)dipalladium(0) (0.1 equiv), xantphos (0.2 equiv) in 1,4-dioxane (0.1 M) was added cesium carbonate (1.4 equiv). The reaction was heated, under microwave irradiation, in a microwave reactor at 150° C. for 2 h. The reaction mixture was quenched with saturated aqueous sodium chloride and then washed with ethyl acetate. The organic phase was combined and washed with saturated aqueous sodium chloride. The organic layer was dried (anhydrous magnesium sulfate), filtered, and concentrated. The crude was purified by silica gel column chromatography (20-80% ethyl acetate (with 10% 1N ammonia in methanol) in hexane). Concentration of the desired fractions under reduced pressure afforded the title compound (64.7% yield) as yellow solid; MS (ESI) m/z 649.6 [M+1]+. The reaction mixture was quenched with saturated aqueous sodium chloride washed with ethyl acetate washed with saturated aqueous sodium chloride The organic layer was dried (anhydrous magnesium sulfate) filtered concentrated The crude was purified by silica gel column chromatography (20-80% ethyl acetate (with 10% 1N ammonia in methanol) in hexane)
