Chloroform → HCID 19907444, compound

Participants

Reaction Steps

To 40 ml of chloroform were added 4.0 g of methyl 4-mercaptobenzoate, 3.3 g of 3-bromo-1-propanol and 2.38 g of triethylamine, and the mixture was stirred for an hour and then evaporated under a reduced pressure. After adding 50 ml of ethyl acetate, the mixture was washed with 30 ml each of water, 1N hydrochloric acid and a saturated sodium bicarbonate aqueous solution, dried over magnesium sulfate and evaporated under a reduced pressure. The residue was applied to a silica gel column and eluted with chloroform/methanol (100:3) to obtain 3.6 g of methyl p-(3-hydroxypropylthio)benzoate as a colorless crystal. To 3.0 g of this crystal was added 1.44 g of phosphorus tribromide, and the mixture was heated at 80° C. for 2 hours, poured into 50 ml of ice-water, and extracted three times with 20 ml of ethyl acetate. The extract was dried over magnesium sulfate, and evaporated under a reduced pressure. The residue was applied to a silica gel column and eluted with chloroform/hexane (1:1) to obtain 3.0 g of the title compound as a colorless oil.
