Reaction Steps

6 ml of 1,3-dimethyl-2-imidazolidone and 0.99 g of sodium hydride at 50% are cooled to +15° C., 2.2 ml of ethyl cyanacetate in 10 ml of 1,3-dimethyl-2-imidazolidone is added over 5 minutes, with agitation for 40 minutes. 4.39 g of cuprous iodide, 3.62 g of 4-iodo-1-trimethylsilyloxy indane and 4 ml of 1,3-dimethyl-2-imidazolidone are added. The mixture is taken to 100° C. for 4 hours. After cooling, it is poured into 100 ml of 2N hydrochloric acid, filtered on celite, and rinsed with water; the filtrate is extracted with isopropyl ether, washed with a saturated solution of sodium bicarbonate and with water, dried and brought to dryness. The residue is chromatographed on silica in a hexane-ethyl acetate mixture (1-1) and 1.22 g of expected product is obtained.
