Procedure
Triethyl amine (1.5 eq.), hydroxylamine hydrochloride (1.3 eq.) were added to a solution of benzyl 1-cyano-7-azabicyclo[2.2.1]heptane-7-carboxylate (C-37) in absolute methanol. The mixture was stirred at room temperature overnight. The solvent was removed under reduced pressure, the residue was dissolved in chloroform and treated with dimethylacetylene dicarboxylate (2 eq.) for 14 hours at 60° C. The reaction mixture was then concentrated and the resulting crude oil was purified by flash chromatography (petroleum ether/EtOAc 1:1) to give the titled compound (C-38) as a mixture of isomers.
