Nitric Acid → HCID 19791105, compound

Participants

Reaction Steps

5.45 g of N-(11-hydroxy-1-undecanyl)-2-(4-ethyl-1-piperazinyl)nicotinamide were suspended in 100 ml of acetonitrile and to the suspension was added dropwise under ice-cooling a mixed solution of 2.0 ml of fuming nitric acid and 5.2 ml of acetic anhydride and stirred for 5 hrs. This reaction mixture was poured into an aqueous sodium hydrogencarbonate solution, extracted with methylene chloride, washed with water and a saturated sodium chloride solution, dried over anhydrous magnesium sulfate and concentrated. The concentrate was purified by silica gel column chromatography (chloroform:methanol=20:1) to give 2.52 g (42%) of the title compound.
