After completion of addition the reaction mixture was stirred for 30 min, then filtered. The filtrate was concentrated to an oil, diluted with hexane (100 mL) and filtered. The resulting filtrate was concentrated to oil and distilled in vacuo. The product was obtained as a viscous liquid (21.2 g, 77%), b.p. 142-145/1 mm Hg.
