実験手順

4.4 g of methyl 8-oxo-9-phenyl-8H-pyrido[1,2-d]thieno[2,3-f][1,4]thiazepine-11-carboxylate were heated under reflux and under argon together with 90 ml of xylene until the reaction was completed. The solution was evaporated in vacuo and the residue was treated with 100 ml of n-hexane, whereupon the product was removed by filtration. By recrystallization from ethyl acetate, there was obtained methyl 7-oxo-8-phenyl-7H-thieno[2,3-a]quinolizine-10-carboxylate as yellow crystals of m.p. 153°-156°.
