Reaction Steps

3-Amino-N-[2-ethyl-4-(1,1,1,2,3,3,3-heptafluoropropan-2-yl)-6-methyl-phenyl]-4-(1H-1,2,4-triazol-1-yl)benzamide (0.2 g) and pyridine (0.05 g) were dissolved in tetrahydrofuran (5 ml). To the solution, ethyl chlorocarbonate (0.04 g) was added under ice cooling. After adjusting to room temperature, the mixture was stirred for 1 hr. The reaction mixture was diluted with water and extracted twice with ethyl acetate. The organic phases were combined, washed with water and dried over magnesium sulfate. After filtering off the drying agent, the solvent was distilled off under reduced pressure to obtain a crude product. The crude product was purified by column chromatography to obtain methyl[5-{[2-ethyl-4-(1,1,1,2,3,3,3-heptafluoro-propan-2-yl)-6-methylphenyl]carbamoyl}-2-(1H-1,2,4-triazol-1-yl)phenyl]carbamate (0.14 g, yield 58%).
