Participants

Reaction Steps

To a N2 purged 50 mL round bottom flask attached with condenser was added 1-(3-chloro-3′-(methylsulfonyl)biphenyl-4-yl)-2-(2-chlorophenyl)-N-(1-hydroxy-2-methyl propan-2-yl)-1H-imidazole-4-carboxamide (361 mg, 646 μmol), anhydrous benzene (20 mL) and P2S5 (720 mg, 3.24 mmol). The reaction solution was stirred at reflux for 1.5 hr. The reaction solution was diluted with EtOAc (100 mL) and filtered through a Buchner funnel to remove excess P2S5. The filtrate was washed with aq. 0.1 N NaOH (60 mL) and H2O (100 mL). The partitioned organic phase was dried over Na2SO4, filtered, concentrated in vacuo, and chromatographed through a 12 g SiO2 column using a gradient of 100% hexane to 95% EtOAc to afford 68 mg (19% yield) of title compound.
