Reaction Steps

N′-(5-{[(2R)-1-(2-tert-butoxyethyl)pyrrolidin-2-yl]methoxy}-2-cyano-4-methoxyphenyl)-N,N-dimethylimidoformamide (300 mg, 0.74 mmol) in acetic acid (0.64 ml) was reacted with (3-amino-1H-pyrazol-5-yl)acetic acid (110 mg, 0.78 mmol) at 120° C. for 20 minutes. The solvent was evaporated, and the residue triturated with dichloromethane to yield {3-[(7-{[(2R)-1-(2-tert-butoxyethyl)pyrrolidin-2-yl]methoxy}-6-methoxyquinazolin-4-yl)amino]-1H-pyrazol-5-yl}acetic acid (183 mg, 47% yield):
