実験手順

72 mg of (S)-(+)-5-oxo-tetrahydrofuran-2-carboxylic acid are dissolved in 2.5 ml of N,N-dimethylformamide, combined with 183 mg of (benzotriazol-1-yl)-N,N,N′,N′-tetramethyl-uronium-tetrafluoroborate and stirred for 30 minutes at ambient temperature. This solution is then added to a mixture of 250 mg of 4-[(3-chloro-4-fluorophenyl)amino]-6-cyclopentylmethoxy-7-[2-(piperazin-1-yl)-ethoxy]-quinazoline and 110 μl of triethylamine in 2.5 ml of N,N-dimethylformamide. The reaction mixture is stirred for five hours at ambient temperature. For working up the mixture is poured onto 50 ml of water. A white precipitate is formed, which is suction filtered and washed with water. The crude product is purified by chromatography over an Alox column (activity stage III) with methylene chloride/methanol (98:2) as eluant. The desired product is obtained as a light-coloured solid.
