N-[(2-aminophenyl)-phenylmethylidene]hydroxylamine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 3.0 g (14.15 mmol) of 2-amino-benzophenone oxime in 120 ml of tetrahydrofuran is treated successively with 1.07 g of potassium hydroxide, 100 mg of tetrabutylammonium bromide, 1.81 ml of dimethyl sulphate and the mixture is stirred at room temperature overnight. The mixture is taken up in methylene chloride, washed with water, dried and evaporated. The residue is twice suspended in boiling ether and filtered off, there being obtained 2-amino-benzophenone O-methyl oxime of melting point 138°. washed with water dried evaporated filtered off
