Participants

Reaction Steps

Benzyl 4-aminopiperidine-1-carboxylate (100 mg) and triethylamine (190 μL) are dissolved in dichloromethane (2 mL), treated with isopropyl chloroformate (920 μL, 1 M solution in toluene) and stirred for 2 hours at room temperature. The mixture is partitioned between dichloromethane and saturated aqueous NH4Cl solution. The organic phase is dried (MgSO4) and concentrated. The residue is purified by HPLC on reversed phase to give the title compound. LC (method 1): tR=1.02 min; Mass spectrum (ESI+): m/z=321 [M+H]+.
