Reaction Steps

The 4-methyl-4-nitropentanoic acid (4.3 g) obtained above was dissolved in dichloromethane, and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (6.1 g) and triethylamine (4.5 ml) were added thereto and stirred for 1 hour. Benzylamine (3.4 g) was added thereto and stirred for 1 day. Water was added to the reaction mixture which was then acidified by 2 N hydrochloric acid and extracted with chloroform. The organic phase was washed with a saturated sodium bicarbonate solution and a saturated saline solution and dried over sodium sulfate anhydrous. The resulting product was concentrated under reduced pressure, and the residue was purified by column chromatography (eluting solvent; ethyl acetate:n-hexane 1:1.5) to give N-benzyl-4-methyl-4-nitropentanoic acid amide (2.5 g, Y.:38%) as a colorless oil.
