実験手順

To a solution of 2-aminothiazole (0.20 g, 2.00 mmol) in dichloroethane (20 ml) was added 1,1′-carbonyldiimidazole (0.40 g, 2.5 mmol) and N,N-dimethylaminopyridine (0.05 g, 0.4 mmol) then the solution was refluxed at 80° C. for 1 h. N-Isopropyl-2-phenoxyaniline (0.46 g, 2.0 mmol) was added and the reaction mixture was then stirred overnight at 80° C. The reaction mixture was concentrated under reduced pressure to afford crude product, which was purified by silica gel chromatography (hexanes:ethyl acetate from 80:20 to 50:50 as eluent system) to afford title product (0.56 g, 79%).
