Yield:2318-82-3 100%

Reaction Conditions:

with hydroxylamine hydrochloride;sodium hydrogencarbonate in water;ethyl acetate at 20; for 0.0833333 h;

Steps:

synthesis of methylbenzohydroxamic acid, CH3-BHA

The synthesis of CH3-BHA is represented in Scheme 1.hydroxylamine hydrochloride (12 mmol, 0.9555 g) was added to a mixture solution of ethyl acetate and water containing sodium hydrogen carbonate (NaHCO3). The mixture was stirred at room temperature. 4-methylbenzoyl chloridewas diluted with small amounts of ethyl acetate was added dropwise to the mixture. The mixture was stirred for 5 min at room temperature. The solvent was removed in vacuo to afford the pure product. Peach solid; yield, 100%; m.p.152-154°C. Anal.
