Wolff, Hans-Michael,Hartke, Klaus
, p. 266 - 279 (1980)
Condensation of the N,N'-dimethylbenzamidines 5 or their lithium salts 6 with o-nitrophenyl substituted aryl fluorides leads to the benzamidines 7.These cyclise on heating up to 100-150 deg C by nucleophilic aromatic substitution to form the benzimidazoli
