実験手順: To a solution of 2-[5-cyano-2-propyl-4-(trifluoromethyl)-1H-indol-1-yl]-N-hydroxyethanimidamide (Example 275A) (0.100 g, 0.308 mmol) in anhydrous acetonitrile (3.0 mL) under N2, was added 3,4,5-trifluorobenzoyl chloride (0.241 g, 1.23 mmol) and N,N-diisopropylethylamine (0.50 mL, 5.21 mmol). The mixture was then heated in a microwave at 150° C. for 30 min. Upon cooling, the mixture was poured onto a biotage prepak column and the mixture was purified by flash chromatography (0-25% EtOAc-hexanes gradient) to give 0.065 g (45% yield) of pure product: MS (ES) m/z 464 (M+). Upon cooling the mixture was poured onto a biotage prepak column the mixture was purified by flash chromatography (0-25% EtOAc-hexanes gradient)

実験手順: To 10 ml of ethyl acetate were added 0.50 g of 3,4,5-trifluorobenzoyl chloride, 0.32 g of cyclohexylmethylamine and 0.50 g of triethylamine and the mixture obtained was stirred at room temperature for 3 hours. The reaction mixture was filtered through Celite. The filtrate was concentrated under reduced pressure. Crystals obtained were washed with a mixture of hexane and MTBE to obtain 0.70 g of N-cyclohexylmethyl-3,4,5-trifluorobenzamide.

実験手順: 3,4,5-Trifluorobenzoic acid (0.176 g, 1.0 mmol) in dichloromethane (1.5 mL) was treated with a solution of oxalyl chloride (1.5 mL of 2 M in dichloromethane, 3 mmol) and a catalytic amount of N,N-dimethylformamide. The reaction was stirred overnight at ambient temperature. The excess oxalyl chloride was removed in vacuo to afford 3,4,5-trifluorobenzoyl chloride. The excess oxalyl chloride was removed in vacuo
