Reaction Steps

280 ml of 28% aqueous ammonia was added to a mixture of 50 g of 4-hydroxythiophenol and 54.56 g of ethylene bromohydrin and the mixture was stirred vigorously at room temperature for 2 h. 225 m(of concentrated hydrochloric acid was added thereto under cooling with ice to adjust the pH of the aqueous phase to 1. After extraction with ethyl acetate, the ethyl acetate layer was washed with a saturated aqueous common salt solution and then dried over anhydrous magnesium sulfate. The resulting solution was filtered and the filtrate was concentrated and subjected to silica gel column chromatography to obtain 44.77 g (yield: 66%) of the intended compound having the following physical properties:
