Methyl chloroformate → HCID 68690594, compound

Participants

Reaction Steps

Diethylisopropylamine (0.98 ml, 5.0 mmol) was added to a stirring solution of (R)-2-benzyl-2-methylpiperazine (0.38 g, 2.0 mmol) and methyl chloroformate (0.41 g, 0.35 ml, 2.8 mmol) in CH2Cl2 (20 ml). After stirring at ambient temperature for 2 h, the reaction was evaporated in vacuo and the residue purified by flash chromatography (SiO2, CH2Cl2 to 40% EtOAc in CH2Cl2) to afford pure product (0.28 g, 34% yield over the two steps). MS (ESI) 307 (M+H).
