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-Methyl-2-phenoxyaniline (0.40 g, 2.00 mmol) was added to the solution. The reaction mixture was then stirred overnight at 80° C. The reaction was monitored by LC-MS and TLC, then concentrated under reduced pressure to afford crude product which subsequently was subjected to silica gel chromatography (hexanes:ethyl acetate from 80:20 to 50:50 as eluent system) to afford title product (0.48 g, 73%) as orange solid. concentrated under reduced pressure to afford crude product which

実験手順: To a solution of 2-phenoxy-N-(t-butoxycarbonyl)aniline (1.43 g, 5.0 mmol) in anhydrous tetrahydrofuran (50 ml) was added lithium aluminumhydride (10 ml, 10.0 mmol, 1.0 M solution in tetrahydrofuran) at −10° C. The mixture was then refluxed at 65° C. overnight. The reaction mixture was quenched with slow addition of MeOH (10 ml) and concentrated under reduced pressure. The reaction mixture was then poured into water (50 ml) and extracted with ethyl acetate (3×100 ml). Organic extracts were combined and washed with brine (2×100 ml) and dried over (Na2SO4), concentrated under reduced pressure to give N-methyl-2-phenoxyaniline (0.94 g, 94.0%) as a pale yellow oil. The product was confirmed by LC-MS and subjected to next reaction without further purification. The reaction mixture was quenched with slow addition of MeOH (10 ml) concentrated under reduced pressure The reaction mixture was then poured into water (50 ml) extracted with ethyl acetate (3×100 ml) washed with brine (2×100 ml) dried over (Na2SO4) concentrated under reduced pressure
