Versuchsvorschrift

A mixture of 20 g of 6,7-dihydro-4-methyl-thieno[3,2-c]pyridine and 19.8 g of methyl 2-methylenephenylacetate was heated under an argon atomosphere to 80° for 2 hours and subsequently to 110° for 48 hours. Methanol was added to the cooled reaction mixture and the product was left to crystallize out. There was obtained 4,5,8.9-tetrahydro-8-phenyl-7H-thieno[3,2-a]quinolizin-7-one of m.p. 159°-161°.
