Reaction Conditions

Reaction Steps

To a rapidly stirred, 0° C., N2 blanketed, solution of 2,2,2-trifluoro-N-(3-methylamino-propyl)-acetamide (6.0 g, 32.4 mmol) and N-methylmorpholine [109-02-4] (7.1 mL, 64.6 mmol) in ethyl acetate (65 mL) was steadily added a 1.0M solution of isopropyl chloroformate in toluene (32.4 mL) over the course of 10 minutes. The reaction was allowed to stir and warm to ambient temperature over night at which time it was washed with brine, dried (MgSO4) and evaporated to provide 9.0 g of clear yellow oil. LRMS (ESI) m/z 271.1 [(M+H)]+, calc'd for C10H17F3N2O3: 270.25.
