Procedure

To a solution of (R)-2-methanesulfonyloxy-methyl-pyrrolidine-1-carboxylic acid, tert-butyl ester (D3) (90 g, 0.32 mol) in DMF (1200 ml) was added sodium cyanide (24 g, 0.49 mol). Heated to 60° C. overnight. Reaction mixture was concentrated and partitioned between water and ether. The organic phase was dried and concentrated to give the title compound (18 g, 30%) (M-Boc) 110.
