Reaction Steps
A 500 mg (2.23 mmol) portion of ethyl N-(3-bromopropoxy)acetoimidate was dissolved in 6 ml of dichloromethane, and the solution was mixed with 0.22 ml (2.23 mmol) of piperidine and 0.33 ml (2.23 mmol) of 1,8-diazabicyclo[5.4,0]-7-undecene and stirred at room temperature for 36 hours. The reaction solution was mixed with a saturated ammonium chloride aqueous solution and extracted with chloroform. The chloroform layer was washed with saturated brine and dried with anhydrous sodium sulfate, and then the solvent was evaporated under reduced pressure. The resulting residue was purified by silica gel chromatography (chloroform/methanol=10/1) to obtain 166 mg (yield, 32%) of ethyl N-(3-piperidinopropoxy)acetoimidate.
