Reaction Steps

A solution of 3-amino-5-(4-methoxyphenyl)-4H-pyrazole (74 mg, 0.39 mmol), (Synthesis, 1984, 3, 276), in isopropanol (3.5 ml) was added to 4-chloro-6-methoxy-7-((1-methylpiperidin-4-yl)methoxy)quinazoline (110 mg, 0.34 mmol) followed by 5M hydrogen chloride in isopropanol (78 μl, 0.39 mmol) and the mixture was heated at reflux for 1.5 hours. After cooling to 5° C., the precipitate was collected by filtration washed with isopropanol, followed by ether and dried under vacuum at 60° C. to give 4-(5-(4-methoxyphenyl)pyrazol-3-ylamino)-6-methoxy-7-((1-methylpiperidin-4-yl)methoxy)quinazoline hydrochloride (133 mg, 72%).
