Participants

Reaction Steps

Tert-butyl piperidine-4-ylmethyl-carbamate (2.00 g) is dissolved in tetrahydrofuran (10 ml), and thereto is added triethylamine (1.69 ml), followed by an addition dropwise of ethyl bromoacetate (1.24 mL) in water bath and the mixture is stirred at room temperature for 2 hours. To the reaction mixture is added a saturated brine, and the mixture is extracted with ethyl acetate. The organic layer is washed twice with a saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure, and to the resulting crystalline residue is added isopropylether and the mixture is filtered to give ethyl [4-(tert-butoxy-carbonylamino-methyl)-piperidin-1-yl]-acetate (1.87 g). MS (m/z): 301 [M+H]+
