Procedure

A solution of [2-(4-tert-Butoxycarbonylamino-phenylamino)-quinazolin-4-yl]-(5-methyl-2H-pyrazol-3-yl)-amine (IIc-60, 100 mg, 0.232 mmol) in a mixture of DCM/TFA (5/1, 12 mL) was stirred for 2 hours at room temperature. The solvents were removed in vacuo and the residue triturated in aqueous K2CO3. The resulting solid was collected by filtration and washed with diethyl ether to afford IIc-66 (69 mg, 90%) as an off-white solid, mp 164-167° C.; 1H NMR (DMSO) δ 2.24 (3H, s), 6.33 (1H, br s), 7.12 (2H, d), 7.48 (3H, m), 7.58 (1H, d), 7.86 (1H, t), 8.64 (1H, d), 10.86 (1H, br s), 11.46 (1H, s); IR (solid) 1681, 1512, 1496, 1433, 1415, 1187, 1129; MS 332.4 (M+H)+
