Reaction Conditions:
in N,N-dimethyl-formamide at 100; for 16 h;
Steps:
50.C Step C: tert-Butyl 3-cyanopyrrolidine-1-carboxylate
A solution of tert-butyl 3- (methanesulfonyloxy) pyrrolidine-1-carboxylate (2.65 g, 10 mmol) and sodium cyanide (2.5 g, 50 mmol) in N, N- dimethylformamide (100 mL) The solution was reacted at 100 ° C for 16 hours. After cooling to room temperature, the reaction was poured into water and extracted with ethyl acetate. The organic phases were combined, washed, dried and the resulting residue was concentrated by column chromatography (petroleum ether: ethyl acetate = 5: 1) to give the title compound (1.92 g, 98%).
