Abstract
1300928 1-Aza-9-oxafluorenes GLAXO LABORATORIES Ltd 30 April 1970 [9 May 1969] 23840/69 Heading C2C [Also in Division A5] Novel 1-aza-9-oxafluorenes are prepared (a) by cyclization of a 2-phenoxy-pyridine-3- diazonium salt (which is unsubstituted in an o-position of the phenoxy group) using a catalyst or by photolysis; (b) by photolysis of a 2-(2<SP>1</SP>-halophenoxy)-pyridine or a 2-phenoxypyridine-2<SP>1</SP>-diazonium salt (which is unsubstituted in the 3-position of the pyridine ring); (c) when a nucleophilic residue is present at the 2- and/or 4-position, by reaction of a 2- and/or 4-halo-1-aza-9-oxafluorene with a nucleophilic reagent; (d) when a nucleophilic residue is present at the 2-position, by reaction of a 2- unsubstituted 1-OR<SP>3</SP>-1-aza-9-oxafluorene quaternary salt, wherein R<SP>3</SP> is an aliphatic or araliphatic group, with a nucleophilic reagent; (e) when an oxygen atom is attached to the ring nitrogen atom, by reaction of a 1-aza-9-oxafluorene with an organic or inorganic peracid; (f) when a 6-substituent is present, by direct electrophilic substitution of the corresponding 6-unsubstituted compound; (g) when the starting material for process (d) above is required, by reaction of the corresponding N-oxide with an aliphatic or araliphatic reactive ester; and (h) when a 4-halo substituent is present, by reaction of a 4-unsubstituted 1-aza-9-oxafluorene-1- oxide with a phosphorus oxyhalide. 2 - Phenoxy - pyridine - 3 - diazonium salts (which are unsubstituted in an o-position of the phenoxy group) are prepared by condensation of a phenol having a free o-position with a 2- halo-3-nitropyridine, reduction of the resulting 2-phenoxy-3-nitropyridine and diazotization of the 2 - phenoxy - 3 - aminopyridine so obtained. 2-(o-Chlorophenoxy)-pyridine is prepared by reaction of o-chlorophenol with 2-chloropyridine in the presence of potassium hydroxide.
