反应条件: temp:0.00; pressure:0.00; stir:

反应条件: temp:120.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of N-[7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-isoquinolyl]cyclopropanecarboxamide (100 mg, 0.30 mmol), 2-bromo-6-fluoro-3-methyl-benzaldehyde (77 mg; 0.35 mmol), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (21 mg, 0.03 mmol) and saturated aqueous sodium carbonate solution (0.1 mL) in acetonitrile (1 mL) was heated under microwave irradiation (Biotage) at 120° C. for 30 minutes. The reaction mixture was diluted with ethyl acetate (30 mL) and washed with water (15 mL). The organic layer was separated, dried over sodium sulfate, filtered and concentrated in vacuo to provide a residue that was purified by flash chromatography (4 g, Silica, 0-60% ethyl acetate in heptane). Desired fractions were combined and evaporated in vacuo to afford the title compound as light brown solid (100 mg, 97%), which was used in the next step without further purification. washed with water (15 mL) The organic layer was separated dried over sodium sulfate filtered concentrated in vacuo to provide a residue that was purified by flash chromatography (4 g, Silica, 0-60% ethyl acetate in heptane) evaporated in vacuo
