Reaction Steps

To a solution of 6-bromo-1-indanylmethanol (20 g) in N-methyl-2-pyrrolidone (NMP) (380 ml) was added CuCN (79 g). The mixture was heated at 160° C. for 6 hours. After cooling to 80-90° C. the mixture was poured into an aqueous solution (500 ml) of NaCN (4g). After stirring for 20 minutes excess CuCN was filtered off. Ethyl acetate (300 ml) was added and the organic phase was separated and worked-up. The remaining oil was dissolved in diethyl ether (300 ml) and washed with saturated brine (2×100 ml). The organic phase was separated and worked up according to the general procedure leaving 14.6 g of crude title compound 2a as a visceous oil. Column chromatography on silica gel (eluent:ethylacetat/heptane 6:4) afforded pure 2a (8.7 g) which was used without further purification.
