Versuchsvorschrift

A 2 liter, 3 neck round bottom flask equipped with a mechanical stirrer was charged with 74.95 grams of the HCl salt of 5-(4-[3-chloro-4-(3-fluorobenzyloxy)-anilino]-6-quinazolinyl)-furan-2-carbaldehyde (prepared according to the Procedure D and Examples 1 (a)–(g), and 749.5 mL THF. To this slurry was charged 84.45 mL of 2M NaOH and the reactants were stirred for 30 minutes. The layers were separated and then the organic layer was washed with 160 mL of H2O. The organic layer was slurried with 3.75 grams of Darco G60 and filtered through celite. The filtrate was collected and slowly added to 33.54 grams of toluenesulfonic acid monohydrate with rapid stirring. The solids slowly precipitated out at ambient temperature. The mixture was cooled to 0° C. and stirred for 10 minutes. The mixture was filtered and pulled dry with a rubber dam, then dried in vacuo at 50° C. overnight. The yield of 5-(4-[3-chloro-4-(3-fluorobenzyloxy)-anilino]-6-quinazolinyl)-furan-2-carbaldehyde tosylate was 84.25 grams (88.8%).
