온도45 °C

반응 단계

A mixture of 100 mg (0.186 mmol) N-(3,5-bis-trifluoromethyl-benzyl)-N-methyl-6-piperazin-1-yl-4-o-tolyl-nicotinamide (Example 53), 0.030 ml (0.42 mmol)2-bromo-ethanol and 46 mg (0.33 mmol) potassium carbonate in 2 ml acetonitrile was stirred at 45° C. for 70 h. After cooling to room temperature 10 ml 1 N sodium hydroxide solution were added. Extraction with 3 15-ml portions of ethyl acetate, drying with sodium sulfate and concentration gave 138 mg of the crude product. Flash column chromatography afforded 85 mg (78.6%) of the title compound as a white solid.
