Komponenten

Versuchsvorschrift

A solution of tert-butyl 2-(aminomethyl)-2-methylpyrrolidine-1-carboxylate (1.2 g), excess 2-chloroacetyl chloride (2 mL) and diisopropyl ethyl amine (2 mL) in DCM was stirred at room temperature for about 2 h. The reaction was monitored by LC-MS. After the solution was concentrated in vacuo, 0.7 g of the desired product was obtained by column chromatography purification. MS (ESI): 291, 293 (MH+).
