Procedure

1.0 g (2.1 mmol) N-[8-(2-chloro-5-iod-phenyl)-4,5-dihydro-thiazolo[4,5-h]quinazolin-2-yl]-acetamide are placed in 50 mL tetrahydrofuran under an argon atmosphere and combined with 0.6 ml (9 mmol) N-methylpropargylamine and 1 mL (6 mmol) diisopropylethylamine. The mixture is kept free from oxygen and 29 mg (0.04 mmol) triphenylphosphine palladium(II)-chloride and 8 mg (0.04 mmol) copper(I)-iodide are added. The mixture is stirred for 5 hours at 80° C. After cooling to ambient temperature the reaction mixture is combined with water and 10% ammonia solution and extracted with dichloromethane. The organic phase is dried and evaporated to dryness. The residue is purified by chromatography, the product obtained is triturated with diethyl ether and suction filtered.
