Sodium hydride → HCID 21434055, compound

Participants

Reaction Steps

0.320 g (7.35 millimols) of 55% sodium hydride dispersion in oil are added by portions, over the course of 15 minutes and while stirring, to 1.02 g (7.7 millimols) of 4-isopropoxybutanol and 1.82 g (7.0 millimols) of 1-(4-bromo-butyloxy)-4-(methylthio)-benzene in 20 cc of absolute 1,2-dimethoxy ethane. The mixture is stirred at 20° for 18 hours and subsequently at 60° for 6 hours. The resulting sodium bromide is suction filtered, washed with ether and the filtrate is evaporated. After chromatography of the residue on silica gel with hexane/ethyl acetate (97:3) and (95:5), 1-[4-(4-isopropoxy-butyloxy)-butyloxy]-4-(methylthio)-benzene is obtained as a colourless oil.
