Procedure

To a suspension of 2,4-Dichloro-6-iodo-quinazoline (3.14 g, 9.66 mmol) in ethanol (200 mL) was added 5-Cyclopropyl-2H-pyrazol-3-ylamine (2.14 g, 19.3 mmol) in ethanol (50 mL) and the partial solution was stirred for 4 h. Filtration afforded (2-Chloro-6-iodo-quinazolin-4-yl)-(5-cyclopropyl-2H-pyrazol-3-yl)-amine (3.21 g, 81% yield). HNMR (500 MHz, dmso) δ 12.39 (1H, bs), 10.97 (1H, s), 9.15 (1H, s), 8.13 (1H, d), 7.45 (1H, d0, 1.99-1.90 91H, m), 0.99-0.90 (2H, m), 0.80-0.70 (2H, m).
