Reaction Steps

A solution of 2-chloromethyl-4-(2-methylbenzyl)-1,3,4-oxadiazolin-5-one (13.3 g) in xylene (35 cc) is added in the course of 20 minutes to a solution of 2-(4-chlorophenyl)-3-methyl-butyric acid (19 g) and triethylamine (11.7 cc) in xylene (175 cc) heated to 110° C. The reaction mixture is heated at the reflux temperature for 4 hours and, after cooling, is washed successively with water (100 cc), a 3.5% strength aqueous hydrochloric acid solution (100 cc), a 4% strength aqueous sodium carbonate solution (100 cc) and water (100 cc). After drying, decolorizing over animal charcoal and concentrating under reduced pressure, the residue obtained is purified by chromatography on a silica column and gives [4-(2-methylbenzyl)-1,3,4-oxadiazolin-5-on-2-yl]-methyl 2-(4-chlorophenyl)-3-methylbutyrate (11.2 g) in the form of an oil.
