Versuchsvorschrift

46 mg of (5H)-furan-2-one are added to a solution of 230 mg of 4-[(3-chloro-4-fluorophenyl)amino]-6-cyclopentylmethoxy-7-[2-(piperazin-1-yl)-ethoxy]-quinazoline in 2 ml of methanol. The reaction mixture is stirred for 24 hours at ambient temperature, then for another six at 50° C. In total, six more drops of (5H)-furan-2-one are added until the reaction is complete. The solvent is distilled off using the rotary evaporator and 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 colourless solid.
