Participants

Reaction Steps

To a solution of 1.58 g (0.00517 mol) 2-(4-methylbenzylseleno)benzoic acid (example 2) and 0.58 g (0.00573 mol) triethylamine in 10 ml dichloromethane which has been cooled to 0° C. is added 1.32 g (0.00517 mol) solid bis[2-oxo-3-oxazolidinyl]phosphoryl chloride in one portion. After stirring for 30 minutes a solution of 0.48 g aniline (0.47 ml; 0.00517 mol) in 10 ml dichloromethane and 0.74 g (1.02 ml; 0.00573 mol) triethylamine in 10 ml dichloromethane is added dropwise with stirring. The reaction mixture is stirred for 20 hours at room temperature and treated with 20 ml distilled water. The organic phase is separated and extracted successively with 20 ml water, two 25 ml portions of 10% hydrochloric acid and two 25 ml portions of 10% sodium hydroxide solution and dried. The solvent is then removed and the residue purified by column chromatography (silica gel/dichloromethane).
