实验步骤: A stirred mixture of 0.8 gram (0.0016 mole) of 4-[bis(4-trifluoromethoxyphenyl)hydroxymethyl]piperidine hydrochloride, 0.3 gram (0.0016 mole) of 4-(2-propyn-1-yloxy)phenylmethyl chloride and 0.5 gram (0.0079 mole) of potassium fluoride on Celite® filter aid in 50 mL of acetonitrile was heated at reflux for about 1.3 hours. After this time 0.5 mL (excess) of triethylamine was added, and the reaction mixture became homogeneous. Upon completion of addition, the reaction mixture was heated at reflux for an additional 18 hours. After this time the reaction mixture was cooled, filtered, and the filtrate concentrated under reduced pressure to a residue, which was subjected to column chromatography on silica gel, with mixtures of 10-70% diethyl ether in hexane as eluants. The product-containing fractions were combined and concentrated under reduced pressure, yielding 0.6 gram of N-[4-(2-propyn-1-yloxy)phenylmethyl]-4-[bis(4-trifluoromethoxyphenyl)hydroxymethyl]piperidine. The NMR spectrum was consistent with the proposed structure. filter aid in 50 mL of acetonitrile was heated at reflux for about 1.3 hours After this time 0.5 mL (excess) of triethylamine was added Upon completion of addition the reaction mixture was heated at reflux for an additional 18 hours After this time the reaction mixture was cooled filtered the filtrate concentrated under reduced pressure to a residue, which concentrated under reduced pressure

实验步骤: 5-Bromo-4-cyclohexylamino-pyrimidine-2-carbonitrile (0.19 mmol) and chloromethyl-4-prop-2-ynyloxy-benzene (0.22 mmol) in DMF (5 ml) are treated with triethylamine (0.56 mmol), copper (I) iodide (0.019 mmol), and dichlorobis(triphenylphosphine)palladium(II) (0.0093 mmol) at room temperature. The mixture is stirred for 2 h at 65° C., poured into an ice water, extracted with AcOEt. The organic layer is washed with brine, dried over magnesium sulfate and concentrated. The crude product is purified by silica gel column chromatography to give the product in 21% yield.
