## Abstract A convenient synthetic pathway to benzo[__g__]quinolines (1‐azaanthracenes) has been developed. The nickel catalyzed coupling of methyl 2‐chloronicotinate (3a) with benzylic organo zinc reagents 2a‐e led to the methyl 2‐benzylic substituted nicotinates 4a‐e. Treatment of methyl 2‐chloro
