Procedure
A solution of 4-(triphenylphosphinemethylenecarbonyl)-1-azabicyclo [2.2.1]heptane (D24) (4 g, 0.01 mole) in dry acetonitrile (80 ml) was treated with m-nitrobenzoylazide* (3.8 g, 0.020 mole) under nitrogen and the solution heated to reflux for 2 h. The solution was then concentrated in vacuo to a gum which was dissolved in ethyl acetate (30 ml) and allowed to stand at 0° C. overnight when the title compound (D25) (1.35 g, 0.0043 mole, 43%) crystallised out.
