Reaction Steps

Ethyl 1-[(4-cyano-1-oxoindan-2-yl)]imidazole-2-carboxylate can be obtained in the following way: a mixture of 3.92 g of ethyl imidazole-2-carboxylate and 3.4 g of 2-bromo-4-cyano-1-indanone is heated at 130° C. for 20 minutes, cooled to 20° C. and dissolved in 20 ml of dichloromethane. The mixture is then concentrated to dryness under reduced pressure (15 mm Hg; 2 kPa) at 40° C. The residue thus obtained is purified by flash chromatography on a silica column, under a nitrogen stream at medium pressure (0.5 bar), with a dichloromethane/methanol (95/5 by volume) mixture as eluent. 1.5 g of ethyl 1-[(4-cyano-1-oxoindan-2-yl)]imidazole-2-carboxylate are thus obtained, which product melts at 159° C.
