実験手順

To a solution of 0.42 g (1.5 mmol) of 3-methyl-5-(3-trifluoromethyl-phenyl)-pyridine-2-carboxylic acid (intermediate 1B) in 15 ml of DMF was added 0.60 g (1.6 mmol) of O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) and 0.62 ml=0.45 g (4.5 mmol) of Et3N; after 30 min, 0.24 g (1.6 mmol) of 4-pyrrolidin-1-yl-piperidine was added. 1 hour later, the reaction mixture was poured into crashed ice and extracted three times with EtOAc; the organic phases were washed with water, dried over magnesium sulfate, filtered and evaporated. The residue was purified by flash column chromatography (CH2Cl2/MeOH 95:5 to 4:1) to give 0.56 g (89%) of the title compound as light brown oil. MS: 418.1 (MH+).
