Reaction Steps

To a solution of the above 4-chloro-2-phenoxymethylquinazoline (0.5 g, 1.85 mmol) in THF (30 mL) is added 3-amino-5-cyclopropylpyrazole (0.47 g, 3.69 mmol) and the reaction mixture is heated at 65° C. for 24 hours. Solvent is evaporated and ethanol is added. A white solid forms and is collected by filtration and dried under vacuum to give (5-cyclopropyl-2H-pyrazol-3-yl)-(2-phenoxymethyl-quinazolin-4-yl)-amine.
