Procedure
70.8 mg of 7-hydroxy-8-phenylthiazolo[3,2-a]thieno[2,3-c]pyridinium hydroxide (internal salt) and 38.2 ml of N-(2-methoxyethyl)-2-propynamide were heated for a long time in toluene under argon. The solvent was removed in vacuo and the residue was chromatographed on silica gel. After recrystallization from ethyl acetate, there was obtained N-(2-methoxyethyl)-7-oxo-8-phenyl-7H-thieno[2,3-a]quinolizine-10-carboxamide as yellow crystals of m.p. 201°-202°.
