Reaction Steps

To stirred and cooled (0° C.) methyl isocyanoacetate (96% technical grade, 1.18 g, 11.9 mmol) was slowly added (S)-(+)-3-fluoropyrrolidine hydrochloride (97%, 1.5 g, 11.9 mmol), triethylamine (1.67 mL, 11.9 mmol) and MeOH (3 mL). The mixture was stirred for 15 h at RT and concentrated. The mixture was stirred for 15 h at RT and concentrated. Water was added (50 mL) and the mixture was extracted with EtOAc (3×50 mL), dried over MgSO4, filtered and evaporated to obtained crude 1-((S)-3-fluoropyrrolidin-1-yl)-2-isocyanoethanone VIB 01166 (1.47 g, 79% yield) as a brown oil which was used in the next step without purification.
