Summary:PURPOSE:To produce high-purity 2-azabicycIo[2.2.1]hept-5-en-3-one from cyclopentadiene as a starting raw material in high yield and economically. CONSTITUTION:2-Azabicyclo[2.2.1]hept-5-en-3-one is produced by a first process for executing a condensation reaction of a substituted sulfonyl cyanide of the formula (R1 and R2 are H, alkyl or halogen) with cyclopentadiene in a hydrocarbon-based solvent and by a second process for treating the condensate with water.
