実験手順

To a solution of 1-(3-bromophenyl)-2-(2-ethylimidazol-1-yl)ethanone (54.6 mg, 0.186 mmol; see step (a)) in toluene (10 mL) and ethanol (1 mL) was added 5-isobutyl-2-(N-tert-butylaminosulfonyl)thiophene-3-boronic acid (101 mg, 0.317 mmol; see Example 1(c)), Pd(PPh3)4 (12.9 mg, 0.0112 mmol), Na2CO3 (373 μL, 0.745 mmol, 2.0 M aq) and the reaction mixture was stirred for 4 h at 80° C. The reaction mixture was diluted with water (10 mL) and extracted with EtOAc. The combined organic phase was dried (over anhydrous MgSO4), concentrated in vacuo, and the residue purified by flash chromatography using MeOH:CH2Cl2 (5:95) as eluent to give the sub-title compound as a colourless syrup in 94% yield (85.5 mg, 0.175 mmol).
