Participants

Reaction Steps

To stirred and cooled (0° C.) methyl isocyanoacetate (96% technical grade, 345 mg, 3.48 mmol) was slowly added 3,3-difluoropyrrolidine hydrochloride (500 mg, 3.48 mmol), triethylamine (487 μL, 3.48 mmol) and MeOH (1 mL). The mixture was stirred for 15 h at RT and then concentrated. The resulting oil was coevaporated twice from EtOAc. 1-(3,3-Difluoropyrrolidin-1-yl)-2-isocyanoethanone VIB 01158 was obtained as a yellow oil (305 mg, 60% yield) and used in the next step without purification.
