実験手順

To 2,6-difluoro-nicotinic acid methyl ester (60, 1.82 g, 0.0105 mol, prepared as described in Example 22, Scheme 24, Step 2) in N,N-dimethylformamide (20.0 mL), under an atmosphere of nitrogen at −40° C., C-(6-trifluoromethyl-pyridin-3-yl)-methylamine (561, 1.00 g, 5.68 mmol) was added. The reaction was stirred at −40° C., then allowed to warm to room temperature for 2 hours. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 35% to 100% ethyl acetate in hexane to give a white solid (562, 1.40 g, 74.9). MS (ESI) [M+H+]+=330.1.
