3-Amino-N-(3-fluorophenyl)-1H-pyrazole-5-carboxamide (153 mg, 0.69 mmol) in dimethylacetamide (1.8 ml) and HCl in dioxane (4 M solution in dioxane, 174 μl, 0.69 mmol) was reacted with 4-chloro-7-(3-chloropropoxy)-6-methoxyquinazoline (200 mg, 0.69 mmol) at 90° C. for 1.5 hour. Dichloromethane (35 ml) was added to the cooled reaction mixture, and the solid recovered by filtration, washed with dichloromethane and dried to yield 3-{[7-(3-chloropropoxy)-6-methoxyquinazolin-4-yl]amino}-N-(3-fluorophenyl)-1H-pyrazole-5-carboxamide (286 mg, 81% yield):
