Versuchsvorschrift

4-(Morpholin-4-ylsulfonyl)aniline (300 mg, 1.24 mmol) was added to a solution of 3 mL of phosphoric acid (85%) and 2 mL of nitric acid (65%) at −6° C. When the mixture reached to room temperature it was cooled to −6° C. and solid sodium nitrite (85 mg, 1.24 mmol) was added during 10 min. Small pieces of ice (50 g) were added into the solution. The mixture was added at 0° C. to a suspension of corresponding 2,4-pentanedione (124 mg, 1.24 mmol) and potassium acetate (20 g) in ethanol (250 mL). The solution was stirred for 15 min, added to 250 mL of a saturated solution of Na2CO3, extracted with dichloromethane, washed with water and brine, dried over Na2SO4, and concentrated under reduced pressure to give 3-{[4-(morpholin-4-ylsulfonyl)phenyl]hydrazono}pentane-2,4-dione (375 mg, 86%).
