실험 절차

To (4-fluorophenyl)(4-(5-methyl-4H-pyrazol-3-ylamino)quinazolin-2-yl)methanone from Example 3 (0.700 g, 2.15 mmol) in EtOH (10 mL) was added methoxylamine hydrochloride (0.336 g, 4.02 mmol) and the mixture was heated to 60° C. for 30 min. Water was added and the yellow precipitate was collected by filtration and washed with MeOH to afford (4-fluorophenyl)(4-(5-methyl-1H-pyrazol-3-ylamino)quinazolin-2-yl)methanone O-methyloxime (0.88 g). LC-MS (ESI) m/z 377 (M+H)+.
