fused pyrido[2,1-a]isoquinoline compounds was investigated. The desired pyrido[2,1-a]isoquinoline derivatives 5, 9, and 10 were obtained by heating 2-(6,7-dimethoxy-3,4-dihydroisoquinolin-1-yl)acetonitrile 1 with ethylacetate derivatives 2, 6, and 7 in refluxing acetonitrile, while piperidine was present as a catalytic quantity. Under the same conditions, compound1 was refluxed with compounds 11a–f
