Phosphorus sulfide (P2S5) → HCID 54411746, compound

Participants

Reaction Steps

A mixture of ethyl 2-[3-[(4-tert-butyl-2-thiazolyl)methoxy]benzoylamino]-4-[3-(4-chlorophenylsulfonyl)propyl]phenoxyacetate (176 mg, 0.26 mmol), diphosphorus pentasulfide (69 mg, 0.31 mmol), sodium bicarbonate (28 mg, 0.33 mmol) and 1,2-dimethoxyethane (5 ml) was stirred for 5 hours with heating under reflux, and insoluble matter was removed by filtration. The resulting filtrate was diluted with ethyl acetate, washed with water and brine in that order, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. Thereafter, the resulting residue was purified by silica gel column chromatography (eluent=hexane:ethyl acetate=3:1-2:1) to give ethyl 2-[3-[(4-tert-butyl-2-thiazolyl)methoxy]thiobenzoylamino]-4-[3-(4-chlorophenylsulfonyl)propyl]phenoxyacetate (143 mg, 0.20 mmol, 78%).
