Versuchsvorschrift
The 3-chloro-5,6,7,8-tetrahydro-6-pyrido [4,3-c]pyridazinecarboxylic acid allyl ester, required as starting material, may be obtained in a manner analogous to that described in Example 8 (g), from 3-chloro-5,6,7,8-tetrahydropyrido[4,3-c]pyridazine maleate and chloroformic acid allyl ester. The oily crude product is used for the next reaction without purification.
