2?-(2-Fluorobenzylidene)-2-hydroxybenzohydrazide was synthesized by the reaction of 2-hydroxybenzoylhydrazine with 2-fluorobenzaldehyde in ethanol. Synthesis of n-aryl indolines from 2-fluorobenzaldehyde dimethylhydrazone derivatives which is an approach to preparation of c(aryl)-n(amine) bond atropisomeric amines. The o-dialkylaminobenzaldehydes were conveniently prepared by nucleophilic displacement of the activated fluorine in 2-fluorobenzaldehyde with the required dialkylamine in hot dimethylformamide. N?-(2-Fluorobenzylidene)-2-(quinolin-8-yloxy) acetohydrazide methanol solvate in the reaction of quinolin-8-yloxyacetic acid hydrazide and 2-fluorobenzaldehyde.
