Reaction Steps
20 mg of Pd/C was added to a round-bottom flask, and the flask was flushed with nitrogen followed by evacuation of the atmosphere under vacuum. To the flask was then added a solution of 2-(4-((S)-4-benzyl-2-isopropylpiperazin-1-yl)-7-methylquinazolin-2-yl)phenol (200 mg, 0.44 mmol) in methanol, followed by the addition of ammonium formate (32 mg, 0.88 mmol). The reaction was refluxed overnight. The reaction was filtered through a bed of Celite to remove the catalyst. The solvent was evaporated to yield 2-(4-((S)-2-isopropylpiperazin-1-yl)-7-methylquinazolin-2-yl)phenol (126 mg). LC/MS: m/z 363.5 (M+H)+ at 2.13 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
