Abstract 2‐Methyl‐3‐(2‐pyridyl)quinoline (1) with a bromomethyl ketone or ethyl bromoacetate yields 6‐methyl‐12‐acylindolizino[1,2‐ c ]quinolinium bromides ( 5–9 ). The acyl derivatives can be deacylated in acid yielding 6‐methyl indolizino[1,2‐ c ]quinolinium salts ( 4 ). Benzoylation of 4 yields the 12‐benzoyl derivative ( 6 ). The deacylation product ( 4 ) has been synthesized from 2‐acetamidophenacyl bromide ( 10 ) and 2‐pyridylacetone ( 12 ).
