Reaction Steps

To 3-(4-fluorophenyl)-3-(4-(5-methyl-1H-pyrazol-3-ylamino)quinazolin-2-yl)propanenitrile from Example 68 (80 mg, 0.21 mmol) in THF (3 mL) at 0° C. was added lithium aluminum hydride (20 mg) and the mixture was stirred for 5 min, then allowed to warm to rt and stir for 2-3 h. An additional amount of lithium aluminum hydride (40 mg) was then added and stirring was continued for 45 min. To the solution was slowly added 1 N NaOH (0.5 mL) followed by MeOH (2 mL). The mixture was stirred for 5 min and then AcOH (0.5 mL) was added, followed by DMSO (2 mL). The resulting solution was purified by preparative HPLC (Varian Diphenyl reverse phase column, eluting with a gradient of solvent B=0.05% HOAc/ACN and solvent A=0.05% HOAc/H2O) to afford 2-(3-amino-1-(4-fluorophenyl)propyl)-N-(5-methyl-1H-pyrazol-3-yl)quinazolin-4-amine as the acetate salt (21 mg, 25%). 1H NMR (300 MHz, DMSO-d6) δ 1.81 (s, 3H) 2.2-2.6 (m, 7H) 4.26 (t, 1H) 6.46 (s, 1H) 7.12 (t, 2H) 7.46-7.51 (m, 3H) 7.73-7.78 (m, 2H) 8.57 (d, 1H); LC-MS (ESI) m/z 377 (M+H)+.
