Reaction Steps

First, 65.1 g of 1,5-pentanediol, 18.6 g of proparygyl chloride, 12.0 g of sodium hydroxide (powdery), 5.69 g of benzyltriethylammonium chloride, and 200 ml of tetrahydrofuran were placed in a reaction vessel, and reaction mixture was stirred for 4 hours with heating under reflux. The reaction mixture was filtered through Celite, and the filtrate was poured into water, and extracted twice with diethyl ether. The diethyl ether layers were combined, washed with water, dried over anhydrous magnesium sulfate, and concentrated to give a crude product. This crude product was subjected to silica gel chromatography, which afforded 12.4 g (yield, 35%) of 5-(2-propynyloxy)pentanol, nD263 1.4533.
