Versuchsvorschrift

Pentafluorophenyl trifluoroacetate (0.867 g, 3.10 mmol) was added dropwise, at room temperature, to a stirred suspension of (4-{[7-(3-chloropropoxy)quinazolin-4-yl]amino}-1H-pyrazol-1-yl)acetic acid (0.800 g, 2.21 mmol) and pyridine (0.245 g, 3.10 mmol) in dimethylformamide (8 ml). After stirring for 5 minutes, aniline (0.412 g, 4.43 mmol) was added and the reaction mixture was stirred for 2 hours. The mixture was poured into dilute hydrochloric acid (0.2N, 25 ml) and the resultant solid filtered and then washed with water. The residue was stirred in dilute aqueous sodium hydroxide solution and filtered and the residue washed successively with water, methanol and diethylether to give 2-(4-{[7-(3-chloropropoxy)quinazolin-4-yl]amino}-1H-pyrazol-1-yl)-N-phenylacetamide (0.520 g, 54% yield): MS (+ve ESI): 437 (M+H)+.
