実験手順
A solution of 2-azaspiro-[5.5]-undec-7-ene (13 g.; 0.086 mole) in benzene (25 ml.) is added dropwise, under ice cooling, to a solution of phosgene (9 g.; 0.09 mole) in benzene (100 ml.). The solution is stirred at room temperature for 1 hour and concentrated under reduced pressure. Distillation of the residual colorless liquid affords 7.5 g. (41% yield) of 2-azaspiro-[5.5]-undec-7-enecarbamoyl chloride, b.p. 110°-113° C./0.50 mm.
