The mixture is a thick green slurry at this point which is treated with THF (15 vols) to dissolve the product that has precipitated, leaving only the Pd/C catalyst out of solution. The mixture is then filtered hot throughGFA filter to remove the catalyst. The vessel is rinsed with IMS (1vol) and the wash used to rinse catalyst bed. A solution of p-toluenesulfonic acid monohydrate (1.50wt, 4.0 eq.) in water (1.5 vols) is added to the filtered solution over 5 minutes at 65C.The reaction solution is cooled to 600C, with crystallization observed at 60-650C. <n="47"/>The resultant slurry is then stirred for at least 1 hour at 600C and then cooled to 20- 25C and then held at this temperature for a further 1 hour. The product is isolated by filtration and the cake washed with IMS (3vols). The product may be stored as a wet cake or dried.
Stage 2: Preparation of 5-(4-[3-chloro-4-(3-fluorobenzyloxy)-anilino]-6- quinazolinyl)-furan-2-carbaldehyde 4-methylbenzenesulfonate A mixture of N-{3-chloro-4-[(3-fluorobenzyl)oxy]phenyl}-6-iodo-4- quinazolinamine (1wt), boronic acid (0.37wt , 1.35equiv), and 10% palladium on charcoal (0.028wt,50% water wet) was slurried in IMS (15vol). The resultant suspension was stirred for 5 minutes, treated with di- isopropylethylamine (0.39vol, 1.15equiv) and then heated to ca 70C for ca 3 hours when the reaction was complete (determined by HPLC analysis). The mixture was diluted with tetrahydrofuran (THF, 15vol) and then filtered (hot - through GFA filter paper) to remove catalyst. The vessel was rinsed with IMS (2vol).

The resultant slurry is stirred for 5 minutes and then treated with /V,Λ/-di-isopropylethylamine (0.396 vols, 1.15eq.). The reaction slurry is heated to 700C for typically 3 hours when the reaction is complete (by HPLC analysis). The mixture is a thick green slurry at this point which is treated with THF (15 vols ) to dissolve the product that has precipitated, leaving only the Pd/C catalyst out of solution. The mixture is then filtered hot through GFA filter to remove the catalyst. The vessel is rinsed with IMS (1vol) and the wash used to rinse catalyst bed. A solution of p-toluenesulfonic acid monohydrate (1.50wt, 4.0 eq.) in water (1.5 vols) is added to the filtered solution over 5 minutes at 65°C. The reaction solution is cooled to 600C, with crystallization observed at 60-65°C. The resultant slurry is then stirred for at least 1 hour at 600C and then cooled to 20-250C and then held at this temperature for a further 1 hour. The product is isolated by filtration and the cake washed with IMS (3vols). The product may be stored as a wet cake or dried.
