The reaction of phenylglyoxal hydrate with acetamidine hydrochloride, propionamidine hydrochloride and butyramidine hydrochloride has been investigated.
When the reaction was carried out in a water solution containing an excess of potassium hydroxide, a compowid was formed that has been shown to be either 2-alkyl-4-phenyl-5-ketodihydroglyoxaline or 2-alkyl-4-phenyl-5-hydroxyglyoxaline. The yield was 70%....
