Participants

Reaction Steps

p-Nitrobenzyl 3-benzylamino-4-methyl-5-phenylthio-2-pentenoate (1.58 g; 3.51 mmole) was dissolved in tolune (5 ml), and trimethylamine (1.06 g; 10.5 mmole) was added thereto at 50° to 60° C. Acetyl chloride (630 mg; 8.0 mmole) was further added thereto all at once, and the resultant mixture was stirred for 10 minutes. Benzene (50 ml) was added to the reaction mixture, which was washed successively with a saturated sodium bicarbonate solution, water, dilute hydrochloric acid and an aqueous sodium chloride solution and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by silica gel column chromatography to give p-nitrobenzyl 2-acetyl-3-benzylamino-4-methyl-5-phenylthio-2-pentenoate.
