実験手順

A solution of 2-(3-piperidin-4-ylidenemethyl-phenoxy)-5-trifluoromethyl-pyridine hydrochloride (0.371 g, 1.00 mmol) (from Example 1, Step 5) and phenyl 6-methoxypyridin-3-ylcarbamate (0.244 g, 1.00 mmol, from Step 1) in DMSO (2.5 mL) was treated with diisopropylethylamine (0.155 g, 1.2 mmol) and heated to 50° C. After 3 h, the reaction mixture was partitioned between water and ethyl acetate. The organic layer was separated and the aqueous layer was extracted again with ethyl acetate. The combined organic layers were washed with brine and dried over sodium sulfate, filtered and concentrated. The residue was purified by silica gel chromatography (10% of the 1N NH3 in MeOH, in dichloromethane) to afford the title compound (280 mg, 58%) as white crystals after trituration in diethyl ether.
