Procedure

Into a 100-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed 1-[(4-[5-[3-chloro-5-(trifluoromethyl)phenyl]-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-2-methylphenyl)carbonyl]imidazolidin-4-one (200 mg, 0.38 mmol, 1.00 equiv), tetrahydrofuran (10 mL), sodium hydride (30 mg, 0.75 mmol, 2.00 equiv, 60%), chloro(methylsulfanyl)methane (149 mg, 1.54 mmol, 4.00 equiv). The resulting solution was stirred for 1 h at 50° C. The reaction was then quenched by the addition of 10 mL of water. The resulting solution was extracted with 3×10 mL of ethyl acetate and the organic layers combined. The resulting mixture was washed with 3×20 mL of brine. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel TLC-plate with ethyl acetate/petroleum ether (1/1). This resulted in 60 mg (27%) of 1-[(4-[5-[3-chloro-5-(trifluoromethyl)phenyl]-5-(trifluoromethyl)-4,5-dihydro-1,2-oxazol-3-yl]-2-methylphenyl)carbonyl]-3-[(methylsulfanyl)methyl]imidazolidin-4-one as yellow oil.
