3-Acetyl-4-methylpyrido[2,1-a]-isoquinolin-2-ones. [2+4] cyclocondensation of 3,4-dihydroisoquinolines with triacetylmethane

Treatment of 3,4-dihydroisoquinolines with triacetylmethane in refluxing alcohol for 2-3 h gave 3-acetyl-4-methylpyrido[2,1-a]isoquinolin-2-ones. Their basic physicochemical properties have been studied.
