Abstract
2-Methylindole condenses with acetophenones under acidic conditions to produce 2-arylanilines in moderate to good yields. The reaction proceeds well with a range of 3′- and 4′- substituted acetophenones (fluoro-, chloro-, bromo-, iodo-, methyl, methoxy), and select 2′- substituted ones (fluoro-, methoxy-). No products were obtained with nitro- substitution in any position.
