Reaction Steps
0.4 g of 4-nitrophenyl 3,4-dihydroquinoline-1(2H)-carboxylate, 0.357 g of 4-spiroindene-piperidine hydrochloride, 0.28 ml of triethylamine and 2 ml of water are introduced into a 10 ml glass tube. The tube is sealed and then heated at 150° C. under microwave irradiation for 50 minutes. Dichloromethane is added. The organic phase is dried over magnesium sulfate and the solvent is evaporated under reduced pressure. The residue is chromatographed on silica gel with a heptane/ethyl acetate gradient from 9/1 to 0/1. 0.393 g of 1′-(3,4-dihydroquinolin-1(2H)-ylcarbonyl)spiro[indene-1,4′-piperidine] is obtained.
