Procedure

A suspension containing 99 g of 3-(dimethylamino)-1-(2-nitrophenyl)-2-propen-1-one, prepared in Example 1, and 63 g of hydroxylamine hydrochloride in 250 ml of ethanol was refluxed for 16 hours, then concentrated to dryness in vacuo. Water (400 ml) was added to the residue, and the resulting suspension was filtered. The solid was recrystallized from 2-propanol to give 60 g of the title compound; m.p. 66°-69° C.
