YieldReaction ConditionsOperation in experiment
With hydroxylamine hydrochloride; sodium methylate; In methanol; EXAMPLE 2 Preparation of 4-Chlorosalicylohydroxamic acid STR50 Hydroxylamine hydrochloride (20.65 g, 0.297 mol) is added to a mixture of sodium methoxide (53 g, 0.99 mol) in methanol while maintaining the temperature below 10 C. A mixture of <strong>[22717-55-1]methyl 4-chlorosalicylate</strong> (46.2 g, 0.248 mol) in methanol is then added to the reaction mixture and the resultant mixture is stirred at room temperature for 10 days, acidified with concentrated hydrochloric acid (pH3) and filtered to give the title product as an off-white solid which is identified by NMR spectral analyses. Using essentially the same procedure, but substituting phenyl 4-fluorosalicylate for <strong>[22717-55-1]methyl 4-chlorosalicylate</strong>, 4-fluorosalicylohydroxamic acid is obtained as a peach-white solid, mp 184 C. (dec.).
