Versuchsvorschrift

A solution of 9,10-dimethoxy-2-chloro-6,7-dihydro-4H-pyrimido(6,1-a)isoquinolin-4-one (2.5 g), 2,6-dimethylaniline (5.0 ml) in butanol (20.0 ml) is heated under reflux for 10 hours. The solvent is evaporated under reduced pressure to give a gummy mass. Chromatography of the gummy mass over silica gel using benzene-ethyl acetate as the eluant gives the required product. The compound is crystallized from methanol, yield 2.0 g, m.p. 297°-299° C.
