6-[(Tetrahydropyran-2-yl)oxy]-1bromohexane (2.0 g) is added, with a mild exotherm, to a stirred mixture of lithium acetylide ethylenediamine (4.9 g) at 20°-25°. The mixture is stirred overnight, then is poured into ice and aqueous ammonium chloride and extracted with ether/pentane. The extracts are dried over magnesium sulfate and concentrated to give the title compound, NMR (CDCl3) 1.3-2.5, 3.3-4.1 and 4.7 δ.
